Ronaldo

I think Manchester United should try to keep Cristiano Ronaldo at the club. He was a very important player the last seasons and he fits just fine in the team's mechanism.
Nani is a player that could grow to take his place in the field, but I think Ronaldo still can achieve good performances with Man. Utd. Also, I don't know if Ronaldo will play as good for Real Madrid, a totally different team,
different players and a different style than MU.

absolutely yes
the player wants to go to madrid he should be allowed to...but only after his contract is completed at man utd

No way at all!

No man u will never ever sell CR from its club at least when CR is at peak form of his career

Impossible is nothing!As we know,Cristiano Ronaldo is very important for Manchester United,but if behoof is much enough,I think Manchester United will sells ronaldo,although I don't think Real madrid needs him.

MU should not sell Ronaldo now, they should wait for few more season. It is too early to sell him off. But money can change the whole scenario.
