Arsenal goalkeeper Jens Lehmann has slammed London rivals Chelsea, claiming that the Blues are an "artificial" football team whereas the Gunners are doing the right thing by building and developing youth.

Chelsea have a virtually blank cheque book when it comes to the transfer market, and have been known to pay over the odds prices for players that they want.

"Our way of working is clearly more attractive," Lehmann explained. "Fans struggle to identify with Chelsea. They are a sort of artificial product.

"Their way of doing things works but they don't play such attractive football. At Arsenal, in that sense, we are a step ahead of them."
