"For the spectator it will have been a great game with a multitude of fans, but for the coaches it has not been so outstanding. There are things to improve, it's obvious. For us, it has been harder.
"The second half they were better, it was more difficult for us to adjust after having had a great first half."
Veteran Jaime Mata again scored and Moreno added: Jaime Mata has worked very hard to have what he has. When a player works like Mata, you are very happy with what happens to him. He is very important for us."
