Cristiano Ronaldo has said he is ``really happy (at Real Madrid'' but admitted that he missed at Manchester United ``a little bit''. The Portuguese winger, who left United for a record £80m fee in the summer, said his challenge was to help Real challenge the dominance of Barcelona as the best club in the world. Sir Alex Ferguson's side have hit a poor patch of form but Ronaldo dismisses the pundits who believe they are struggling without him. ``I think Manchester United are doing very well this season,'' said Ronaldo, ``they have lost the last two games but they are still second in the league. ''What people think about me is their opinion but I really miss Manchester a little bit as I played there for six years and I left a few friends there. So I miss the club a little bit but I'm focused now at Real Madrid and I'm really, really happy there.`` Ronaldo said Barcelona, whose victory in the Club World Cup at the weekend made it a staggering six trophies in the last year, have to be regarded as the best club in the world. ''Barcelona have won everything this year so have to be the best club at the moment,`` he added. ''Barcelona have a style of play and players who have been playing together for many years so they are an outstanding team. But we will do at our best at Real Madrid to win the league and Champions League. It's going to be difficult but in football everything is possible if you work hard and dedicate yourself to that endeavour.`` Looking ahead to next summer's World Cup, Ronaldo tipped England as one of the potential winners. ''In my opinion, England have a fantastic team, they had a great qualification campaign,`` he said. ''They have a good coach and have every opportunity to do a great job in South Africa. ``It's not just England. Spain are really strong as well and Brazil are always there. Portugal also have their chances. At Euro 2004 nobody spoke about Greece and they won the tournament. You never know. I look forward to having a great World Cup and I'm really focused.``
