No but the PL is an infinitely bigger platform than Ligue 1 to showcase his talents. This would've been the ideal time to make the move given he's 25 years old. Everton has a track record of not standing in the way between their standout players and a move to bigger things if he would've performed there (think Onana, Ndiaye, Lukaku, Fellaini, Stones, Richarlison, Gordon, ...).
Now he needs to have a(nother) good season at Monaco and he'll likely still get shipped off given his contract expires in 2028, but I don't see what he has gained by not signing his contract. Other than getting to live another year in Monaco instead of NW England of course, but I'm talking purely from a career/football POV.
