Chelsea boss Jose Mourinho has claimed that Radamel Falcao will be determined to prove his doubters wrong at Stamford Bridge this season.

The Colombian international, who joined on a season-long loan deal from Monaco, endured a miserable time at Manchester United last term.

Falcao scored just four times in 29 appearances for Louis van Gaal's side, and Mourinho thinks that the South American will be determined to establish himself as one of the world's elite strikers once more this term.

Mourinho told reporters: "It's his motivation [to prove people wrong]. When you are not a top player, you never feel frustrated. When you are a top player, you have to live with this all through your career and you adapt to it.

"We felt his frustration. He is not happy that in England people think he is not as good as he is and his motivation is there.

"He did a lot of things to come to us. He lost money to come to us, he didn't want to listen to other offers. He helped us a lot to do a deal with Monaco so, all these things together, we think we can help him and he can help us."
