Cristiano Ronaldo has dismissed Sir Alex Ferguson's claims that Manchester United will fail to pull off an incredible Quintuple.

The Manchester United boss believes that winning five trophies this season is beyond his all-conquering stars.

But World Player of the Year Ronaldo insists United are ready to add the Champions League, Barclays Premier League and FA Cup to the Carling Cup and Club World Cup they have already secured.

'We’re positive about all the competitions we're involved in and we want to win them all,' said Ronaldo. 'It would be great to achieve that.

'Last season we won the league and the European Cup, and this year we have the opportunity to do even better. We’ll continue working hard and we believe we can do this.'

The Red Devils are currently four points clear in hand in the league with a game, while the European draw for the quarter-finals takes plave tomorrow. They are also two Wembley victories from lifting the FA Cup.

Fergie said: 'The thing about cup football is you need to be the best but you also need a lot of luck, and I think it's asking a lot for all the games to go your way.'
