Alex Hleb accepts he cannot be guaranteed a start at Barcelona.
The former Arsenal midfielder said: "I must be patient because Barca is full of great players and everybody wants to play regularly.
"I just want to play as often as I can for this team."
Hleb says he's been able to settle quickly thanks to the presence of former Gunners teammate Thierry Henry.
"He's helped me a lot about the club, we are not only friends but our families are also close."
