Valencia defender Gabriel Paulista had no complaints after defeat at Real Betis on Sunday.
Betis were comfortable 3-0 winners on the day.
Paulista said: "It was a very difficult game, in which we started well defensively, with a lot of control. However, we lacked possession of the ball and patience when it came to stealing it back and going on the counterattack. We conceded from a set piece, something on which we are working hard, and conceding a goal like that is a tough pill to swallow.
"We have to learn from the bad things we did. Diakhaby is an important player and we are having quite a few problems with injuries right now. We have to continue, we have important players who are able to help and solve these problems we are having."
He added: "We cannot drop our heads; there is a long way left this season and we have to learn and continue working because this has only just begun."
