Based on ratings only Mbappe is ahead of him this season
He's definitely been more of a playmaker but in terms of goals hasn't helped that he's hit the woodwork quite a few times
You were comfortably second last season, so you haven't improved with his signing, though I'm not saying that's necessarily his fault but you can't say the signing has worked out
Even if they do get promoted (still a lot for them to do) it will have been after 4? seasons in League 1, that's embarrassing.
Ironically even back to back promotions will have meant 6 in a row outside the top division.
