Colombian striker Radamel Falcao insists that he will continue fighting at Manchester United despite him not getting too many first team opportunities this season.

The 29-year-old striker, who completed a £6 million loan switch from AS Monaco last summer has not been handed a start by Louis van Gaal since United's 2-0 win over Sunderland last month. Furthermore, he has only scored four goals in 22 appearances this season.

As a result, it doesn't look like the Red Devils are going to take up the option of permanently signing Falcao for £43.5 million at the end of the season.

However, the former Atletico Madrid striker, who was earlier considered to be one of the most lethal strikers in the planet, says that he has still not given up hope on his Manchester United career.

"I just need to play. I can't let myself get worried - I need to be prepared to take the opportunity when it comes," the striker told Colombian radio station Radio Caracol.

"I am happy at the club and with how the fans and my team-mates have treated me. I will keep fighting until the end at Manchester United."

The former Porto striker, who suffered a bad knee injury last year, says that he holds no grudges against manager van Gaal even though the Dutchman has not given him many first team opportunities this season.

"He has to make decisions in the same way any other coach does, and whether or not they're favourable to me I just try to do my job professionally at all times," added the Colombian.

"My personal relationship with him is difficult to sum up - every coach has a different way of handling a group of players and they are to do with 'culturas' [cultural differences or approaches to the game], different ways of thinking and different philosophies. I have a completely normal relationship with him."

However, Falcao, who is currently preparing with Colombia for their upcoming friendly fixtures against Bahrain and Kuwait, admits that he has to sit down and decide where to go next if the Red Devils do not sign him on a permanent basis at the end of the season.

"When the championship finishes, of course I will sit down, analyse things and decide what is best for me," Falcao added. "Obviously I need to find a place where I have continuity and where I can play. I am totally focused on the club. There are eight games left and anything can happen."
