Real Betis boss Gabriel Calderon has insisted that he has "no concerns" about his side's mentality ahead of the upcoming Europa League last-16 encounter with rivals Sevilla.
The first leg of the derby takes place in Seville on March 13, at a stadium where they have lost 5-1 and 4-0 on each of their last two visits.
"I have no concerns, but I won't know until the time of the game, what the attitude of my players is like. We have an important collective job to do," he told reporters.
"What we're looking for, is that something like what happened at Valencia, doesn't happen again, though I no longer have the impression that we can concede five again."
Betis currently sit 20th in La Liga, while Sevilla are seventh.
