Sunderland midfielder Craig Gardner has welcomed the arrival of Danny Graham.

Gardner believes Sunderland now have a bigger threat in attack following the £5m acquisition of Graham from Swansea City.

"Danny's a class act," he told "You can see when he comes onto the pitch he works his socks off and he's there sniffing out chances and looking for goals.

"We've got [Steven] Fletcher up front and [Stephane] Sessegnon firing balls forward. There's competition for places all over the pitch which is a good thing for Sunderland Football Club."
