that's a matter of opinion isnt it , i remember the pundits of MOTD (their expertise can be doubted i know) claiming that Dembele is the one player that was most missed.We miss Sandro more than we missed Dembèlè tbh
but i for one also expect more from him and its true that his phyiscal presence has been a bit on the weak side lately , normally he'd lose almost no duel and now he seems to be panicking a bit when the challenges come in.
