Barcelona are facing a crunch decision over Palmeiras defender Yerry Mina.

While Barca have an option on the Colombia international, it doesn't guarantee he will end up at the Nou Camp.

Sport says AC Milan and Bayern Munich have been watching Mina this season and sounded out his agents about a move to Europe.

Among his representatives is Mina's uncle, Jair Mina, who has confirmed there is a "preliminary agreement" with Barca.

Mina would already be a Barca player this season, but the youngster was reluctant to start his European career with Barca B.
