Barcelona coach Ronald Koeman revealed in the pre-match press conference against Getafe that Alba is missing and new aid Deste may start as a left-back.
Koeman said: "First of all he joined the training class very well, we have time to talk to him about the team's system, and this system is not too different from his Ajax."
"We know that he can be a right-back, he can also be a left-back. We know that Alba can't come back tomorrow, so he might start tomorrow."
The former Dutch national team coach added: "He stayed in the team and did not participate in the national team matches to help him adapt well to the team. For him he can adapt to everything about Barcelona better because of all the things here. Both are bigger than Amsterdam."
"He is a very good signing to join the team because he is one of the future players of this club.
