Okay, I was more than willing to believe our recruitment messed up given our history with midfielders, so I checked on Mandragora, but... does he just do a lot of stuff that doesn't show up on the stat sheet or something?
Passing (Mandragora left, Amrabat right):
Possession:
Defending:
Worse at short, medium and long passing (check out that 60% success rate on long!), seems to have a higher proportion of his touches in the attacking third rather than defensive, isn't much of a carrier, defensively doesn't seem a whole lot different to Amrabat either... he got 2 goals and 4 assists in Serie A last year, is that why he's a better midfielder? Doesn't seem a stand-out, at any rate.
I usually dislike these kind of stat-offs, but it seems a little bit of an egregious comparison in this case.
