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.
