Valencia coach Ruben Baraja was left frustrated after their 4-2 defeat at Barcelona on Monday.

Los Che goalkeeper Giorgi Mamardashvili was sent off and Baraja took issue with Barca's third goal on a controversial night.

Baraja said: "There have been different games. We have played a great first half, at a high level. Barcelona has helped us because they were their mistakes, although we forced them.

"The expulsion of Giorgi [Mamardashvili] was vital for us. And that together at the start of the second half, with the score at 2-2. And we had the score at 2-3 in Diego López's action, we have to be more forceful. And then Lewandowski scores a quality goal by sending it to the corner. A great rival and we were with ten.

"Barcelona is bottling you up, they are giving you corner fouls. But they have scored goals in corners against Real Madrid, against PSG. And when they took the lead on the scoreboard it was very difficult.

"In the third goal I think there is a positional offside position that I wouldn't know how to assess very well. The action is very fast, I don't know what the referee decides, they comment on it and give a goal. This may or may not be he makes the gesture of wanting to touch the ball a little. You would have to look through the archives to see what was called. Sometimes in a field it is called and other times, it is not."

He added, "In different fields there are situations in which a decision is made and sometimes others are based on the referee's interpretation. And that's what baffles you.

"It could be positional offside. Or Araujo's is yellow because it was a promising chance."
