Man U sour grapes - look at Saha's move to OT. Madrid haven't tapped the player up - i.e. approached him directly. They have just made the whole world, including CR, aware of what they're willing to pay.

Fergie knows that he's lost Ronaldo because he wasn't a good enough manager to keep him.

This is real rich coming from Man U; Ferguson, notwithstanding the rather pretentious 'Sir' Fergie will always be what he really is - a publician - a person lacking in tact and class, precisely what he accuses RM of lacking. Does he not recall his pursuit of Hargreaves, Carrick, etc....

FIFA will not do anything. They are paid by the clubs who generate bigger revenues through increasing the media coverage of football. Stop the media frenzy and this fuss will go away.

Gareth Loggenberg, Chatham, UK

Please! United don't tap up players anywhere as badly as RM who are repeatedly making their desire to sign Ronaldo public and using the media's influence to unsettle him. Fergie admires Berbatov but he's not 'obsessed' about signing him like Calderon is. RM simply don't know when to back off.

Dew, London,

Typical, having tapped up players themselves over the years, when it happens to them the great manchester united start bleating. !! They realise that without Ronaldo they are just ordinary.

Did Man U also report themselves for doing the same to Spurs over Berbatov? I doubt it.

FIFA will do nothing as either way they make money.

Wardy, Lisbon, Portugal

Why does it take a club to report another for anything to be done? I'm neither a Man Utd fan or a RM fan, but for pities sake, surely the governing body reads the papers? Shouldn't they be pro-active rather than reactive? Is it any wonder people don't think this kind of situation will ever end?

andrew, darlington,

About time too. The club employed the same tactics with Anelka, Zidane and Figo to name a few. Hopefully a wrap across the knuckles will have the desired effect and they will back off.

Harry, Manchester, England

Man Utd like everyone else in the footballing world knows that going to FIFA is a waste of time. They simply won't do anything! The only reason Man Utd have done this is to show their intent that they will not sell Ronaldo, at least this year.

Raza, London, UK

Waste of time going to FIFA. They don't even like English clubs - look at the attitude of people like Blatter and Platini. In fact they will probably open the doors wider for Real. And the contracts are a waste of time. Might as well pay the the players on a weekly basis and forget any paperwork.

Peter, Conwy,

Even though I'm not an MU fan, I feel that RM have acted with no honor in this instance. Never making a direct approach, they have instead made leading statements, leaked stories about CR 'dreaming' of a move to RM and what they will pay him, even used his mother in this. They deserve punishment.
