Arsenal midfielder Gilberto Silva has backed manager Arsene Wenger's transfer policy.

Gilberto said: "It's a big gamble when clubs spend big money for each new season but we do not spend.

"But while we haven't spent a lot of money, we have been playing together for a few years now.

"That makes a difference in the game because we all know each other - if I pass to Cesc Fabregas he knows exactly where the forwards will be. That's important.

"We must keep focused because other clubs have made some very good signings.

"Arsene has his policy of signing players and he does what he believes is right for the club.

"He spends as little as possible and that helps the club when they do need to spend money."
