In every window there is at least one player at the centre of a transfer slugfest, testing the resolve of his current employers while showcasing club loyalty with all the sincerity of an air hostess' smile.
Manchester City's Carlos Tevez becomes the latest in a long line of prolonged Premier League transfer sagas. Following a similar pattern to previous cases, the striker's future continues to remain unclear amid a barrage of speculation and rumour.
AC Milan, Inter and Paris Saint-Germain make up the three-horse race to sign the Argentine but the trio have weaved cautiously through negotiations thus far. City, meanwhile, insist they will not let Tevez go cheaply, despite his unwillingness to even train with the club.
But while we're all familiar with Tevez's circumstances, the 27-year-old is not the first player guilty of drawing out his own future beyond reasonable lengths, subsequently subjecting us all to the monotony of a 'will he, or won't he?' guessing frenzy.
DAVID BECKHAM TO REAL MADRID, 2003
A stray boot to the face, kicked by Sir Alex Ferguson, left David Beckham with two stitches above his eye and edged him closer to the exit door at Old Trafford in February 2003.
Beckham's future under Ferguson continued to look bleak after the incident as he started on the bench for Manchester United's Champions League quarter-final second-leg tie against Real Madrid, a club strongly linked as a potential destination for the midfielder. Beckham did his chances of a move to the Bernabeu no harm by notching two goals after coming on, one a superb free-kick which left Iker Casillas rooted to the spot.
Despite his performance in April, at the end of the month Real Madrid president, Florentino Perez, claimed the club would 'never, ever sign Beckham', which placed Barcelona as frontrunners for the midfielder's signature.
After another month of speculation, Barcelona's then presidential candidate, Joan Laporta, claimed an agreement had been reached over the transfer of Beckham, although the player's advisors claimed he was being used as a 'political pawn' in the Camp Nou electoral race.
That setback for Barcelona left negotiations clear for Real Madrid, who eventually went on to sign Beckham for £24.5 million in June. Despite appearing to leave under a cloud, Beckham publicly thanked Ferguson for his support, though the United boss later claimed the midfielder 'was never a problem until he got married'.
STEVEN GERRARD TO CHELSEA, 2005
Gerrard had secured a Champions League winners' medal after inspiring Liverpool to a remarkable comeback against AC Milan in May 2005 and went on to admit he was eager to begin talks over a new contract.
Links from the previous summer with a move to Chelsea appeared to have been banished, as both Rafa Benitez and the club's then chief executive, Rick Parry, urged Gerrard to stay, revealing a contract extension had been offered.
But talks dramatically broke down. Liverpool later issued a statement confirming Gerrard had rejected their offer, while the midfielder added that his intentions to sign a new deal after the Champions League final had changed.
The U-turn reignited Chelsea's interest, sparking a £32m bid from the west London side, while reports from Spain suggested Real Madrid were also weighing up a heavy offer for the midfielder.
But just a day later, Gerrard had a change of heart again and insisted he wished to stay at Anfield. Contracts were reworked and the Liverpool captain signed a four-year extension in July 2005.
ASHLEY COLE TO CHELSEA, 2006
Over a year before his confirmed arrival at Stamford Bridge, Ashley Cole, along with two agents, Jose Mourinho and former Chelsea chief executive Peter Kenyon, were caught in a secret meeting and subsequently fined by the FA in one of the highest-profile 'tapping-up' cases to date.
Arsene Wenger branded Chelsea as 'arrogant' over their illegal attempts to sign the left-back, while Arsenal chairman Peter Hill-Wood revealed Cole demanded a triple-wage increase in order to stay at Arsenal.
Despite signing a contract extension in July 2005, Cole joined Chelsea just over a year later for £5m, with William Gallas moving the other way.
In his autobiography, Cole believes Arsenal 'fed him to the sharks' during the tapping-up case for not publicly backing him over the incident.
THIERRY HENRY TO BARCELONA, 2007
"I've never played in Spain and now I never will. This is my last big contract," was Thierry Henry's declaration after signing a four-year extension at Arsenal in May 2006.
Two days before his commitment, Henry cut a frustrated figure after losing out to Barcelona in the Champions League and the striker fuelled speculation over his future after failing to commit to the club in a post-match interview.
After winning a second runner-up medal just over a month later, this time in the 2006 World Cup final, Henry's final campaign at Arsenal was ended in March due to a groin injury. Following David Dein's departure from the club the following month, Henry admitted he was 'devastated' by the decision but remained adamant he would stay at the Emirates for the remainder of Wenger's reign.
Despite his promise, Henry completed his move to Barcelona in June 2007, while Wenger insisted there was no animosity between himself and the forward following his exit.
CRISTIANO RONALDO TO REAL MADRID, 2008-2009
A blistering record of 42 goals in a total of 48 appearances for Manchester United in the 2007-08 season initiated Real Madrid's interest in Cristiano Ronaldo, although after winning the Champions League with Manchester United at the end of the campaign, the forward insisted he wanted to stay at Old Trafford.
United, agitated by Madrid's public attempts to lure Ronaldo, filed a complaint to Fifa during the summer which was later dismissed. Ferguson reiterated the forward will remain at Old Trafford for the following season.
Speculation continued to increase and in response to claims that United and Madrid had made a secret deal to sell Ronaldo to the Bernabeu the following summer, Ferguson said: “Do you think I would get into a contract with that mob? Jesus Christ, no chance. I wouldn’t sell them a virus."
Ronaldo's last game in a United shirt came in the 2009 Champions League final defeat to Barcelona, and transfer tittle-tattle sparked once again as a summer of uncertainty loomed.
Florentino Perez, who returned as Real Madrid's president, vowed he would not to be deterred by Ronaldo's hefty price tag, though his words were put to the ultimate test after securing the services of Kaka for a reported £56m in June.
Later that month, Ronaldo expressed his desire to leave Old Trafford and United accepted the £80m bid lodged by Real Madrid. The forward was unveiled officially in July, arriving at the Bernabeu for a world-record transfer fee.
CESC FABREGAS TO BARCELONA, 2010-2011
The back-and-forth nature of transfer talk involving Cesc Fabregas became almost metronomic throughout the midfielder's proposed switch to Barcelona.
Hill-Wood started off proceedings in April 2010, claiming Barcelona had assured the club they would not submit a bid the following summer. Txiki Begiristain, Barcelona's former dealmaker, dismissed any promise had be made and a £27m bid launched in June was met with a resounding rejection from Arsenal.
Fabregas insisted he wanted his future to be decided before he left for Spain's World Cup campaign but Barcelona remained firm on the midfielder's valuation, while a host of the Camp Nou playing personnel, notably Gerard Pique, Xavi and Carles Puyol, publicly courted the Arsenal captain.
Fabregas, meanwhile, confirmed he would remain loyal to Arsenal (despite being pictured in a Barcelona shirt whilst celebrating Spain's World Cup victory) and stayed at the Emirates for the following season, although his final campaign under Wenger was blighted by a persistent hamstring injury.
As the transfer window approached, Fabregas admitted he held talks with Wenger over his future, but the Frenchman remained firm, labelling Sandro Rosell's claim that the midfielder's valuation had decreased as 'disrespectful'.
Barcelona opening gambit of £30m was rejected in June, and Arsenal maintained their resilience. Puyol went on to liken Fabregas' situation at the Emirates to that of a prisoner but the midfielder seemingly put an end to speculation at the start of August by confirming his commitment to the club.
But Fabregas' statement of intent did little to dissuade Barcelona and the midfielder went on to leave Arsenal for £35m, signing a five-year deal at the Camp Nou.
LUKA MODRIC TO CHELSEA, 2011
A showcase of a club's resolve to retain their prized asset, Tottenham stared in the face of increased bids, transfer requests and public wantaway declarations from Luka Modric to keep the midfielder at White Hart Lane
Chelsea initially lodged a bid of £22m which was rejected by Spurs, while a £27m improved offer, which was also declined, sparked an official transfer request from Modric, as the Croatia international claimed the club's chairman, Daniel Levy, had broken a gentleman's agreement to sell him to a bigger club in the summer.
Both Levy and manager Harry Redknapp continued to stand firm over Modric, as the Spurs boss continually referred to the Tottenham chairman's no-sale stance when questioned on the midfielder's future.
Tottenham's resilience, which was tested one last time after a deadline-day bid of £40m from Chelsea, paid off as Modric admitted he would stay until the end of the season, but talks over an improved contract have yet to evolve into an official commitment from the 26-year-old.
SAMIR NASRI TO MANCHESTER CITY, 2011
Perhaps Arsenal should have paid the price for failing to renew Samir Nasri's contract, as Manchester United and Manchester City closed in on the France international, whose deal at the Emirates was due to expire in June 2012.
Paul Scholes declared Nasri had the ability to fill the role he had retired at Old Trafford at the end of last season and the void in United's midfield suggested the 24-year-old had the chance to become a pivotal figure in Sir Alex Ferguson's plans.
But the financial clout of City eventually prevailed as the midfielder moved to Eastlands for a reported £24m fee, while picking up a salary which dwarfed the contract offers from United and Arsenal.
Nasri's parting shot directed at his former club hit out at the Emirates board for restricting Wenger in the transfer market. Arsenal may have considered themselves fortunate after making over £10m on a player who had only a year left on his contract.
WESLEY SNEIJDER TO MANCHESTER UNITED, 2011
Wesley Sneijder constantly remained open to a potential move during last summer, even up until August 30, the Netherlands international claimed a deal could be struck in the closing stages of the transfer window which would to bring him to Old Trafford.
Ferguson, however, remained coy throughout the process, refusing to be drawn into speculation. After the close of the transfer window, the United boss insisted the 27-year-old 'was never an option' when targeting a midfield replacement for the retired Scholes.
Sneijder later revealed he was close to joining United and would have had no objections to a move to the Premier League.
CARLOS TEVEZ TO AC MILAN, 2012
Trouble had begun to brew as early as April 2010, less than a year into Tevez's arrival at Manchester City.
The Argentine had criticised Mancini over his training methods but worse was to come as the club rejected a transfer request from the striker in December and followed up eight days later with a statement suggesting Tevez had withdrawn his initial plea, with the forward pledging his commitment to City.
Speculation continued to mount and in June 2011, Tevez spoke in an interview about how he would not return to Manchester 'not even for a holiday'. The striker followed up with a subsequent statement issuing his desire to leave Eastlands in order to be closer to his family.
Corinthians appeared to be the perfect suitors but despite an agreement being reached between City and his former club, Tevez's transfer to the Brazilian side fell through. Inter, Real Madrid and a return to Boca Juniors remained possible destinations but a deal failed to materialise.
Tevez remained a City player but was stripped of the captaincy by Mancini and was limited in his appearances by the form of Edin Dzeko, Mario Balotelli and summer signing Sergio Aguero.
Tevez's next move was to spark a one-man mutiny as he refused to come off the bench during City's Champions League defeat to Bayern Munich. An angry Mancini vowed the Argentine would never play for the club again, while his fine of four weeks' wages as a result of a club investigation was halved by the Professional Footballers' Association.
Since the beginning of the January transfer window, City have fired a warning shot to potential suitors by revealing Tevez has lost £9.3m in wages, fines and bonuses this season after going on strike.
Despite the revelations, Inter, Paris Saint-Germain and AC Milan remained undeterred in the race to sign the Argentine, although the latter have already broken off negotiations with City previously this month after Alexandre Pato confirmed he was staying at San Siro.
