Barcelona goalkeeper Victor Valdes says the fans have every right to be angry after Saturday's 3-2 defeat to Real Betis.

Over 200 supporters greeted Barcelona's squad back from Seville with angry protests and later Valdes admitted: "We know that we have returned after failing. We had a great opportunity to move into the leadership, but we failed to clinch a match that was very much in our control.

"I fully understand the unhappiness of the fans.

"I am with the coach when he says he was ashamed."
