Valencia boss Nuno has revealed his frustration after Sunday's 1-0 defeat to Barcelona at the Mestalla.

Sergio Busquets scored a stoppage-time winner for the Catalan outfit and Nuno has claimed that the defeat for Los Che was undeserved.

"We lost the match in the final seconds and did not deserve this result. We had a good match like we hoped we would and created chances in the second half," he told reporters.

"We were very well organised and dealt with almost everything they threw at us. We knew the quality of our opponents. I'm deeply frustrated, and the players are too.

"We had moments when Barca's possession forced us down the pitch, but we also had times when we pressed high. We left Mestalla saddened by the loss. The team did their fans proud. With this kind of performance, we'll win many more games."

Valencia have now lost their last two in La Liga.
