Arsenal goalkeeper David Ospina has defended Colombia teammate Radamel Falcao over his problems at Manchester United.

Falcao failed to get off the bench in last night's FA Cup defeat to the Gunners.

Ospina told the London Evening Standard: "He has demonstrated that in every team he has ever played in.

"When he has stability and continuity, he will come to the forefront and he is going to be an amazing player for Manchester United. We will never underestimate him.

"He is an excellent forward and I will hope to stop him scoring any goals against us if I play."
