Rio Ferdinand says Manchester United are set for great things - if they can keep their best players.

"The most important thing is for this team and for this squad to stick together," he said. "If we can do that and add to what we've got, then we've got a great chance of sustained success.

"In football these days you never know what's around the corner. But if we can keep our best players and the core of the side, we can go on to great things."
