Enrique refused to be too hard on his players despite the disappointing performance, but the Spanish coach conceded that he 'was not happy' with what he saw in Alicante.
"They wanted to win but we have experience in this kind of knockout tie. As much as I'm not happy, we tried to create problems for a team who changed its system to put five players in defence," Enrique told Mundo Deportivo.
"We struggled in the first half, we were pretty bad. In the second half we created more chances and could have won but the tie is open and you have to wait for the second leg. Now we focus on one of the best games that can be seen in the championship and we are motivated to face our rivals."
