Carlos Cuellar is delighted with his move to Sunderland.

The defender has signed as a free agent after coming off contract at Aston Villa.

Cuellar told SAFC TV: "Ever since I heard the rumour that Sunderland were interested in signing me, I wanted to come here.

"To work again with the gaffer, Martin O'Neill, and with everyone talking so well about the club, I didn't have any problem and said straight away I wanted to come.

"He is so clever, he knows everyone very well and knows how to push everyone to get 100% out of them.

"He gets the best from every player and brings them together to make his teams very competitive."
