The Colombia international has managed just one goal this season but says if he had regular football he would prove his worth
The Colombia international moved to Stamford Bridge on loan in the summer after spending a season with Manchester United and scoring just four times.
However, Falcao has suffered similar disappointment with the Blues, managing just one goal in 11 appearances for the champions but has bemoaned his lack of playing time.
"I have recovered from my knee injury," he told Semana. "The problem is since then I have not had the chance to play a whole season to get back my confidence and become competitive again.
"If I had had that regular football, you would not be saying this right now.

Falcao also insisted his current injury is not connected with his knee and should not keep him sidelined for too long, despite Chelsea coach Guus Hiddink recently claiming the problem was "very serious".
"Everyone is free to express their opinions but I think that journalists should do it with more responsibility. They lack accuracy," he said.
"Today they do not go to the source to confirm the news and say things that are not true. The only thing they haven't said yet is that Falcao is going to play in a team outside the Earth."
