Despite appearances, Monaco did want to sell him from the beginning, mainly because he did want to renew his contract.
If he plays, the risk of being injured exists, which could endanger a transfer
IMO Monaco did want to present him as a "bad boy" to make the fans understand a move.
At the end, Monaco wishes all the best for him on Twitter.
Regarding his mindset, he has a healthy spirit like Trezeguet, Henry for example. On the contrary, players like Anelka/Benzema/Menez/Ben Arfa were very talented at a young age but let's say their personalities are "complex" (big ego, complacency...)
