The main problem is that he`ll probably be used in a swap deal and not many teams want him due to his age.
PSG might still want him but the only one I could think of is Icardi and thankfully he distanced himself from the move.
Man Utd - This is the perfect club to trade with as they have Pogba who also wants out according to reports and we all know Allegri likes him.
The only problem (or in this case a good thing) is there is now way in two lives Glazers are paying his salary. Even if CR was to reduce his demands to let's say 40-50m gross (which I think even 50m is low but ok) they are not paying that. No chance.
PSG maybe if Mbappe leaves, but I am not sure how much Ronaldo would want to go there honestly. With everything I still think he chooses us over PSG. And PSG just gave Neymar the same salary Ronaldo has with us. Can they really afford to pay 2 players 100m in wages? All rumors so far suggest they want to redeem Kean and get two fullbacks (Hakimi and Theo Hernandez) which would cost them 150m plus all together.
Maybe it's wishful thinking but I still struggle to see who is paying that for Ronaldo at 36. I really don't see it.
And in any exchange we'd have to add a ton of money on top of CR.
