The top five flops of the season

The curtain came down on yet another entertaining Barclays Premier League season yesterday. New signings like Robin van Persie and Michu proved crucial in delivering their respective teams success, but a number of big transfer signings backfired.

Here, Press Association Sport's Paul Hirst takes a look at the five biggest transfer flops of the season.

ROBERT GREEN (QPR)

Green spoke of his excitement at joining Mark Hughes' ambitious project last summer, but this year could not have gone much worse for the 33-year-old. After a wobbly opening game against Swansea, Hughes had seen enough and made a move for Inter Milan stopper Julio Cesar. Green was furious with Hughes, and was made to sit on the bench for most of the season. Harry Redknapp's arrival meant Green played more often, but he could not stop the team sliding towards relegation. Redknapp now wants the former West Ham goalkeeper, who just 12 months ago was playing for England in the run-up to Euro 2012, to be his number one in the npower Championship next term.

JOSE BOSINGWA (QPR)

A real car crash of a season for the Portuguese right-back. This time last year he was picking up his Champions League winner's medal with Chelsea, but he has now become a real hate figure at Loftus Road after a dismal campaign. Mark Hughes thought Bosingwa's pedigree as a double Champions League winner would add experience and skill to his back four, but the 30-year-old, who earns £65,000 a week, put in a series of error-strewn performances and he then incensed Harry Redknapp by refusing to sit on the bench against Fulham. The former Porto defender enraged Rangers fans and Joey Barton by smiling shortly after the draw at Reading which sealed both clubs' relegation.

ALOU DIARRA (West Ham)

Once hailed as the next Patrick Vieira, West Ham thought they had snapped up a real bargain when they signed Diarra for £2million from Marseille last summer. The 31-year-old penned a three-year contract with the Hammers but he failed to settle and was shipped out on loan to Rennes in January after making just one Premier League start. The Frenchman said he had been made false promises by an agent who set up the deal and he also claimed he had never held a proper conversation with manager Sam Allardyce during his six-month spell at Upton Park.

SCOTT SINCLAIR (Manchester City)

Roberto Mancini was desperate to sign Robin van Persie last summer, but instead he got Jack Rodwell and Scott Sinclair. Neither have impressed at City this season, but Sinclair has probably just been the bigger flop. Sinclair started the season at Swansea, where he scored eight goals last term, before City signed the midfielder for £8million. He was substituted in his first two games for the club in September and has not made a Premier League start since. Before he was sacked as manager, Roberto Mancini the Team GB midfielder could leave in the summer.

PAVEL POGREBNYAK (Reading)

Fulham were desperate to sign Pogrebnyak following a successful loan spell from Stuttgart, but he opted for a more lucrative deal at Reading. The Russian started well, scoring four in his opening eight matches, but his form dipped thereafter and he ended the season with just five Premier League goals and a ticket to the npower Championship. Reading team-mate Adam Le Fondre was playing for npower League Two side Rotherham less than two years ago, but he managed 13 goals this season.
