After the 1-0 loss, Keylor called for his teammates to stay focussed and to keep giving their best over the remaining 12 rounds of LaLiga action.
"The circumstances aren't in our favour, but we have to be professionals and know that you don't have to be close [to the leaders] to come out for a match motivated," he said after the full-time whistle.
"It's logical that we are sad, as we wanted to win.
"We have to learn from these matches.
"I don't view this as a step backwards because sometimes you win and sometimes you don't.
"We need to show character to move forward."
