Atletico Madrid midfielder Fran Merida insists they can upset Barcelona at the Nou Camp.

Merida is convinced they can end Barca's 15-match unbeaten run.

"We have had a difficult week, but the manager [Quique Sanchez Flores] has been giving us his ideas and although Barca are a strong side at home, we have great weapons and great players," the 20-year-old said.

"We can win the game.''
