On balance I agree with Maupay, but Bissouma has only just started turning in undroppable performances and Pröpper has clearly flattered to deceive at times this season.Personally I’d add Bissouma, Propper and Maupay to the essential spine
Pröpper, Mooy, and Bissouma are all capable of being world beaters for 2 or 3 games and then anonymous for the next 2 or 3.
