article: You don't have to be an avid follower of Manchester United to know that Radamel Falcao has struggled badly at Old Trafford this year. Goals have been hard to come by for the Colombian, with just four being netted by the striker this season in a United shirt having signed on a season-long loan from Monaco. But not only has Falcao failed to score since January 31 against Leicester, he has also failed to have a shot on target in the Premier League - featuring in 10 games since.During that period he has collected £3,080,000 in wages.

Granted, Falcao has not always featured for the Red Devils but the striker's £280,000-a-week wages are a massive burden for United, making a permanent move this summer even more unlikely despite the uncertain future of strike partner Robin van Persie. Falcao started in Manchester United's 1-0 defeat at Chelsea on Saturday, but despite playing the full 90 minutes for a side that bossed over 70 per cent of the ball, he struggled to get involved in the game. The striker saw a shot blocked by Gary Cahill and had another two shots fly wide in the second half. But otherwise the Colombian's biggest impact was a negative one as he lost the ball following a John Terry challenge in the build up to Eden Hazard's winning goal at Stamford Bridge. Following another failed audition in front of manager Louis van Gaal, Falcao's Premier League adventure is set to go down as a costly mistake for the Red Devils. John Terry had the upper hand on Falcao in their personal scrap, with the Chelsea captain winning the ball off the striker to start a move which led to Hazard's goal in the Premier League clash .
