Manchester United boss Sir Alex Ferguson echoed centre back Rio Ferdinand's claim that a clean sweep of all four major trophies could be within United's grasp.

He said: "We have a good squad plus a few decent young players for the League Cup and back-up in the Champions League, so we'll have a go.

"We've known about Nani for a long time. When we signed Ronaldo, he was the next player in Sporting's set-up that we were keeping an eye on."
