Daniel Alves is full of praise for young Barcelona teammate Sergi Roberto.

Roberto has been standing in for Alves while he was injured.

"I'm not surprised by Sergi Roberto. In this squad there is a lot of quality and all the players are ready to play anywhere.

"I'm happy for him, because he is an option in this position. All are welcome and also what they do is they force the first choices to strive to do even better.

"We must all compete and that's good for everyone."
