Really? Dude set on the bench for the entire season and now people want instant results?
Remember how a young Dollarumma gave away goals every two months?
He definitely has more potential than Krunic. Keep him until the next coach decides his fate.
What more minutes might help is positioning in defensive battles, which he messes up regularly, but it doesn't change that he is so slow both in pace as in body movement. Someone tempodribbling at him - he is in trouble. Someone accelerating away from him - no chance of catching up or even making enough contact to slow him down. He is only really good in defensive situations were he can run at someone and his sluggish body is already in movement and decision making is limited.
Also Musah is 2 years younger, had one game where he made grave blunders but has moved on form it and has been solid in defense, Adli is not that far from expiring, he needs to step up.
He is actively costing us points at this point and it is now getting to a point where he deserves to be called out for it. He is a CM Hauge and Pioli´s initial judgment was right, if you like it or not.
Both he and Krunic need to be sold, this is not a Adli or Krunic, Adli manages perfectly fine to suck on his own.
