Let me ask you a question, which young player Allegri gave a chance more than that odd sub here and there?
And by the way, I don't think this is on Allegri. It's incriprted on Juventus walls. No matter what manager arrives it will be the same.
I don't think thats very fair to Allegri. He is not a very youth-oriented manager, but he also gives good playing time when there are interesting youngsters imo.
Kean was 18 or 19 when he got significant game time for us the first time around and it earned him a 30m move to the PL
I remember El Shaarawy and De Sciglio were teenagers when they broke through with Allegri at Milan.
Dybala was 21 or 22 when he joined and was an instant started for Allegri, same for De Ligt.
Rugani iirc was like 21 or 22 and he carved a lot of game time in his first two seasons or so back when he was promising. Same for Bentancur.
Then there are lots of ~23yo that are/were starters for him like Locatelli, Chiesa, Can, Bernardeschi, etc.
I do hope he brings more minutes to younger players since some of the established ones are so disappointing.
