Is C. Ronaldo a slave?

Recently, Ronaldo has been linked to a record-breaking transfer to Real Madrid. Ronaldo made known to the world about his desires to play for Real while FIFA president Sepp Blatter labelled Ronaldo as a 'slave'.

In a normal circumstances, a club would tight their key players into long-term contract, in protecting the club's interest. Personally, I think there is nothing wrong by doing unless the pay is very low. Ronaldo is receiving six-digits wages every week and he signed the contract without being forced.

On the other point of view, the fact that Ronaldo wants to play for Real is undeniable. Nothing wrong for a player for wanting to play for his favourite club. It is not good for the player and the club if the player feels uncomfortable at the club and forced to honour his contract.

Thus, IF I were the manager of MU, I would choose to sell Ronaldo for few reasons:
1- He is not loyal to MU anymore, his heart is at Real side.
2- He is highly-valued,MU could have massive transfer budgets after selling him.
3- He is just a world class player, not a LEGEND!! A world class player could change the game
but a LEGEND could change the team.
4- He is having the worst injury in his career, no one can guarantee that he will back to the top
level again after recovering from the injury.
5- Real's players do not welcome the signing of Ronaldo. His presence might destroy the
harmony of Real team.
6- Selling him to Real is better than selling to Chelsea.
