From what i gather he’s had offers from Saudi, Roma and Fenerbache. Probably others, maybe premier league.
But he seems fixed on top tier european teams - PSG or Bayern - likely as he can coast, maintain reputation. Both of which arent paying a fee and huge wages.
The hold up there is that he likely wants United to bare the brunt of it - he gets his wages paid, the club of choice - while united say thankyou for saving his wages.
The club might see it as better to have him in the squad - score a few worldies and win us a couple of games rather than let spurs or arsenal pay the same wages and get the return.
