Colombia coach Jose Pekerman has told Manchester United manager Louis van Gaal that he will rebuild Falcao's confidence.

The 29-year-old striker, who will link up with his national team this week, has struggled to find his best form since moving to Old Trafford from Monaco on loan last summer.

Pekerman has revealed that Falcao is unhappy with his current predicament, but he is confident that the frontman will find some form in games against Bahrain and Kuwait next week.

"It's a huge problem that we need to resolve. This problem is as large as the sadness that Falcao is going through right now," the Manchester Evening News quotes Pekerman as saying.

"I feel I need to support him because I understand how hard it is for him and the difficult moment he is experiencing. I want to work with him again and help him restore his confidence.

"I know Falcao's strengths, his mentality and his fighting spirit and I've never doubted that he'll come out the other side. He's in a bad moment, but he's looking after himself and this week is going to be very important for him."

Falcao has scored just four times for United this season.
