Rio Ferdinand is convinced Manchester United are stronger when Wayne Rooney has a striker to play alongside.

Ferdinand told the Observer: "I honestly think that if Louis Saha had been fit all season we probably would've won the league earlier - he's that vital to us, and a player of that type is important to us.

"Wayne did a great job, but his game is more around having that free role to roam rather than having to stay up there, even though he can do it. He scored 15 or 16 goals, and had 15 assists, so he didn't do a bad job."
