Athletic Bilbao boss Joaquin Caparros says his side put in their best performance of the season.
The victory, Caparros says, came from his side scoring two early goals in the first half.
"We played a very good game. We had a lot of rhythm and created plenty of chances," the coach told AS post-match. "We had the reward of scoring two goals early on and that gave us confidence.
"Furthermore, in the second half, we kept pushing forward and creating chances."
The most pleasing thing for the coach was that nine of the starting XI players this evening had also played against Alcorcon during the week.
"I must also highlight the resilience of the players after the effort on Thursday, as it could not have been easy," concluded Caparros.
