He'd want a signing fee and big wages so not really free.
Of course you will bake that into the the equation. This is the way football works. If you'd have to buy a forward of this quality (ignore the age now) you'd probably have to reach up to 50-60m euro. So there's a lot of room for wages when the transfer fee is out of the way.
It's a market out there and it all comes down to what we can offer. If we're in the CL and Mourinho is here I'd say there's a quite big chance he might join us.
China - No way, his brand would be totally demolished.
USA - That would be like going to bed before 6 in the evening. There's absolutely no challenge there for him. Only reason could be to build himself a name, pure commercial reasons so to say.
PSG - Is an alternative but quite a boring one. I think he's done and wants to move on.
Italy - This would be the biggest disappointment. He's already done this before and only have things to lose by going there.
Then there are a couple of english clubs he might consider. City, Chelsea and Arsenal. I think it would be a step down from where he is today in terms of winning the CL. If he wants to play in england he should obviously play for Man United or nothing at all.
Sorry Alock1 for this overdone post. I just couldn't stop myself.
