Manchester United can win the Quintuple this season, insists Cristiano Ronaldo. Sir Alex Ferguson's side added the Carling Cup yesterday to the Club World Cup.

They also head the Premier League by seven points, are in the quarter-finals of the FA Cup and are in pole position in the Champions League.

Ronaldo insisted: "It is quite difficult to achieve but we are going from game to game.

"We always have the opportunity to win everything. We've won this cup and now we don't have much time to celebrate."
