Bentancur is a talented player with low football IQ, just like Rabiot and Ramsey. He lacks timing in challenges, passes and positioning. Without a proper system and razor sharp instructions he´s a fish out of water.
Ironically enough I think that´s why he was better under Sarri last year, cause like it or not Sarri gave him exact patterns to follow. This midfield isn´t smart enough to play in a hybrid and make adjustments on their own, they need an autocratic coach with a clear system.
KDB, Kimmich etch are high IQ players who can think the game on their own and fit in a hybrid system. These Juve players are the exact opposite, and Pirlo is the worst kind of coach for them.
