They all have experience. Yet it barely means something. You can see plenty of experienced coaches who fail to deliver. Conte achieved huge success here yet he had only several years under his belt. Del Neri, Ranieri and others had a 5 page CV yet brought a disaster upon us.
And I never said we should get somebody who'd coach us first. But old fossils are not a solution.
I actually think he has pre planned subs that he sticks to no matter what. He has no idea how to adjust in game or change formation or tactic mid game.
