Former Arsenal midfielder Mathieu Flamini believes Cesc Fabregas deserved to be named the Gunners' new captain.
Spain international Fabregas was handed the armband on Monday after William Gallas was relieved of the duty following controversial comments about his team-mates.
Flamini spent four years at Arsenal, enjoying his best form at Emirates Stadium last season, before signing for Italian giants AC Milan in the summer.
The Frenchman was in action in Thursday's 2-2 Uefa Cup draw at Portsmouth and, speaking after the game, he backed Arsene Wenger's decision to appoint Fabregas as skipper.
He told Sky Sports News: "I am not surprised by the choice. I have talked with him [Fabregas] a bit about it and he is very happy.
"It is great for him, for the club and for the fans. He is a big player in that team. I think he deserves it."
When asked if he understood Gallas' criticism of his team-mates, Flamini said: "It is difficult to say. William Gallas wanted maybe a reaction from his team-mates.
"It is never easy to know what to do. Maybe it will be positive and there will be a reaction from the team."
Of Arsenal's testing start to the season, he added: "Big clubs can have difficult periods. But there is a lot of quality at Arsenal so I am sure they will go forward.
"The important thing is to keep working hard and I am sure they will be okay. They have some amazing players."
