Barcelona coach Xavi admits new signing Vitor Roque is yet to be registered with the LaLiga.

There's doubts about whether Barca have room in their wage ceiling to fit in Roque without selling another player.

Xavi said, "The registration process is missing, as I am told. I count on him and he will be on the call. I guess it will be a matter of hours. He will be called (against Las Palmas).

"We will go little by little, obviously. He is an 18 year old boy and we cannot pressure him.

"He's okay. He has been taken care of and arrived well. He has professionalism and attitude. We will be cautious."
