His subs as in...his bench...or his sub decisions?
Either way I disagree:
1.) The Bench = depth + rotation applied during congested fixture list
2.) The subs in two instances kept Juventus in the game with a victory against Genoa after being a goal behind, and then vs. Chelsea when being 2-0 down away at the Bridge.
The latter having many people perplexed as to how Conte is managing his team and in-game decision making while being banned!
