Robbie Savage compares Radamel Falcao's situation to that of Fernando Torres

Falcao had a big reputation when he arrived in England but hasn't delivered, while Torres's form declined rapidly when he left Liverpool for Chelsea.

Former Premier League midfielder Robbie Savage believes that Manchester United's Radamel Falcao is suffering a loss of form and confidence to the same degree as Fernando Torres did during his time at Chelsea.

In his column for the Daily Mirror, Savage believes that the Colombian's most recent injury troubles compare to that of the former Liverpool striker as he has struggled in front of goal this season, only finding the net four times during his spell at Old Trafford.

Savage also accused United boss Louis van Gaal of disrespect in leaving Falcao on the bench in the 2-1 defeat to Arsenal in the FA Cup on Monday, with the forward instead lining up against the Tottenham under-21s the following day.

He said: "Falcao was one of the most exciting forwards in the world before he missed last summer's World Cup with a serious injury.

"Clearly he is struggling to regain that half-yard of pace which set him apart from the crowd - in the same way that Fernando Torres laboured after his knee injury in 2010."

It is hard not to make such a comparison given that Torres's form basically fell off a cliff in the final six months of his time at Liverpool before moving to Chelsea for £50 million, and his problems at Stamford Bridge are well documented given that he became a figure for a ridicule more than anything.

Falcao's lack of form since arriving in the UK is a symptom of the difficulties United have faced this season which puts them in danger of missing out on the Premier League's top four yet again as performances from Louis van Gaal's side haven't been very convincing.

Some forwards can return from injury and never really be the same again. Torres is an example that Savage has mentioned but there are others. But even with injuries, there are chances the Colombian perhaps should have done better with - one that springs to mind is a chance in their away trip to West Ham at the start of last month.

One could suggest that Falcao's problems this season have been mental as well as the physical demands of returning from a serious knee injury and adapting to a new side in a different league.
