"Manchester United think he is worth it. They made their mind up before the World Cup and now they've got what they wanted.It's a colossal amount but they've got their man and that's vital if they are to make a challenge for the championship they lost last year.He's left a very good club - I spent 7½ years there - but Manchester United are a fantastic club.He handled the move from West Ham well and he'll blossom into an even better player now.He wants to play in the Champions League and didn't achieve that at Leeds. But he's grasped the opportunity to play with a club who can get that on a yearly basis.Rio had a very good World Cup and enjoys playing against the best. Now he has the opportunity to achieve that ambition - which all professional footballers should try and do.
