January is a busy time for Premier League managers to conduct business, as they attempt to strengthen squads in the battle to avoid the drop or shore up their ranks for a title challenge.
And deadline day is the busiest, with last-minute signings often either proving a masterstroke or an utter disaster.
FOX Sports Asia takes a look at some of the worst transfer deadline-day dealings in the recent history of the Premier League.
Fernando Torres, Liverpool to Chelsea, January 2011
Undoubtedly one of the worst, Torres arrived at Stamford Bridge from Anfield for £50 million after hitting 65 goals in 102 games.
But he never discovered the same form in Blue, despite numerous false dawns, and left four years later after having bagged just 20 goals in 110 Premier League games for the Blues.
Even the Champions League semifinal winner against Barcelona was not enough to save Torres from going down as one of the biggest deadline-day flops of all time.
Robinho, Real Madrid to Manchester City, September 2008
The diminutive Brazilian arrived at the Etihad for £32.5 million just after the takeover by rich Arab owners, even though it was thought he was going to Chelsea. The Londoners were probably glad that they missed out as Robinho failed to live up to the hype despite a decent start to his career in Manchester. After a series of injuries he left the club just two years later to return to Brazil.
Andy Carroll, Newcastle to Liverpool, January 2011
The giant Geordie made the switch to Liverpool on the same day that Torres went to Chelsea. Signed as a replacement for Torres, the £36-million Carroll enjoyed a torrid time at Anfield and netted just six goals in 44 appearances before being shipped off to West Ham two years later.
Juan Cuadrado, Fiorentina to Chelsea, February 2015
After a great World Cup for Colombia the previous year and some sparkling form for Fiorentina, the winger arrived at Stamford Bridge to much fanfare for the small sum of £23.3 million. The honeymoon didn’t last long however, and he was promptly sent out on loan to Juventus after just 13 appearances for the Blues. He has been there ever since.
Xisco, Deportivo La Coruna to Newcastle, September 2008
The Magpies shelled out £5.7 million pounds for the Spaniard after a prolific spell with Depor and he scored on his debut for Newcastle against Hull. But that was as good as it got for Xisco, who made just 11 appearances in four years at St. James’ Park before his contract was terminated. Xisco is currently plying his trade for Muangthong United in Thailand.
