Barcelona coach Xavi hailed matchwinner Joao Felix after victory over Atletico Madrid.
Felix, on-loan from Atletico for the season, struck for the 1-0 win.
I've seen him working hard, stealing many balls, and he links up well with Cancelo on the wing," said Xavi.
I'm happy for him, I see him happy and that makes a difference. I told him to be calm because these 'extra motivations' sometimes take their toll on you.
I am delighted to have him on the team."
