I wonder what the Arsenal opinion on this is now?
Scenarios: best to worst for Arsenal
1) Extends his Arsenal contract: Likelihood 10%
2) Joins City. They get a replacement. Maybe Mahrez. Likelihood 45%
3) Sees out his contract but announcement mid season, going to a European club. Likelihood 45%
They probably want and expect 3, but in my opinion that's the worst scenario because of the season-long distraction (to the player and fans), and loss of morale.
I am not sure about my likelihoods. Everyone seems to think that we are in for him - but there are no bids. And logically the deal that makes sense is that for Mbappe, not Sanchez (for me anyway).
