He's played it when he has had the players. At Juve he had 3 class CBs and a stacked midfield. At Chelsea as of right now, he wont have good enough in central defense (as I think it was Alcaraz said)
I agree. The one thing Conte obviously is, is a tactical master. He will see two things: a) He hasnt got the time or the players at Chelsea to implement a 352. b) That the 352 is not suited to the pace and general style of the EPL/English football
