Barcelona assistant coach Eusebio Sacristan says Bojan Krkic must be patient about breaking into the first team.

Eusebio said of the Spain U17 striker: "It's impossible for a player of his age to play with continuity. He needs to remember what Leo (Messi) did.

"Let's hope he returns from South Korea with an open mind. The loss of Sammy (Eto'o) will open the door for him."
