He can go to BL (Bayern), go back to EPL (no new challenge) or to Ligue 1 (very weak league).
We are the best club in Italy by a margin and have a great history. He won everything in the EPL so I dont think he will return.
If we are willing to foot his salary, we should be as attractive as Bayern now. He can single handedly make Serie A relevant again with his star power and he'd pay for himself in no time.
