Sergi Roberto says he's ready to step in at Barcelona for Daniel Alves.

Roberto featured in victory at Athletic Bilbao after an injury suffered by Alves.

"It's always tough on this field [but] we got the three points.

"If Dani Alves is out and the coach gives me the opportunity to play at that position I'll play there and try to give my best to help the team beat Málaga, get the three points, and achieve the ultimate goal, which is to win the league."
