Barcelona coach Xavi says they're in contact with Athletico Paranaense regarding Vitor Roque over a potential knee injury.

Roque broke down early against Internacional last night after receiving a heavy challenge.

The teen was stretchered off and eventually substituted.

Amid claims of a knee injury, Xavi said: "We are in permanent contact with the doctors in Brazil. We'll see.

"Bojan (Krkic, loan manager) will be in charge, from now on, of following up on loaned footballers or with buyback options."
