4. Radamel Falcao
The player that Falcao was before his knee injury and after just shows how fragile the career of a footballer really is. The Colombian was at the top of the world with his exploits at Porto, Atletico Madrid and Monaco but that injury seems to have robbed him of all his ability to score goals.
Falcao now seems like a player who is on a ride just waiting for the game to end. He barely contributes to his side and it was a surprise to see him sign, on loan, with Chelsea and Jose Mourinho. This didn’t really work out for either player and it is likely that Falcao will move back to Monaco in this transfer window.
