I think what we would have to pay him, and pressure from sponsors would mean he would have to play most of the time.
And I also think we are too big of a club to have players, however great they were, winding down their career's in our team.
Juve and Ronaldo, big gamble by Juve to bring him in and win the Champions League and it's failed.Now Ronaldo's crazy contract is killing Juve. I also think Ronaldo in terms of condition/fitness is well ahead of Messi.
I agree with what your saying and fitness and age is my point.
Not a chance he will come to England and play 50+ games.
I'm pretty sure sponsors etc will know that.
