Stuttgart midfielder Alex Hleb has warned new Barcelona signing Dmytro Chygrynskiy he faces a major battle to be a success at the Nou Camp.

"In Catalonia, the people who live there are very patriotic and the Ukrainian (Chygrynskiy) will have to speak their language (Catalan) to be accepted fully," said the former Barca midfielder.

"His exploits on the pitch do not guarantee that they will accept him."
