If we are still interested in him I think we're playing it perfectly.
On the wave of last season and all of the comments from the managers of top teams, Monaco created a hugely wild and frankly idiotic valuation of him. Slowly but surely, these teams have dropped off. Arsenal seemingly made a bid which wasn't enough so bought Lacazette, Madrid have been open that they would need to sell to bring him in and none of their stars (or mostly Bale) are prepared to move and it's perhaps a year too soon for them. That left us and PSG. Pep has mentioned his interest and since then we've been quiet, stony quiet.
Now, Monaco are left with a problem. Their valuation is lunacy and the bidding war they anticipated has not happened. As things stand (and from what's reported), PSG are the only club at the table (and even they seem to be distancing themselves) - the last club Monaco would want to sell to. There's also questions around PSG's ability to afford such a transfer after Neymar although that's another conversation entirely.
They need to sell him this year. They've shown their hand by leaving him out of the starting eleven for the Dijon game and by not pushing him to commit to a new deal. As it stands, they've a player they aren't playing, on a low wage, with now new contract likely and no buyers bar PSG. From a position of seeming power, Monaco are now in a weak position.
I would not be surprised in the slightest if he ended up here for circa £80mil with a few add-ons.
