Steven Fletcher admits Jermain Defoe's arrival has lifted everyone at Sunderland.

Defoe made his debut in defeat to Tottenham on Saturday.

"There is a buzz about the training ground and the fans are delighted to have a massive signing like Jermain," the Scotland international, who played in a front two with Defoe, said.

"He is a great player and I think hopefully a few of the boys will learn off him as well.

"We changed our formation a bit for the game and it was working well but we switched off for a minute and they punished you with a great finish.

"Obviously we got a bit more space. When there is one up front you are surrounded by three men and we just thought it was better for me and Jermain to get some more space, so hopefully in games to come we will get to know each other better."
