Arsenal fans will love to watch their beloved team again if a manager
whose tactical awareness is on the high side because wenger has no plan B in every game, he leaves his step son Ozil who is playing bad and remove Iwobi or anybody just because his tactics is configured.
Formations are only one part of a
tactical set - up, and Klopp is a manager
whose own philosophy is built around timing,
awareness, positioning, and an ability to perform certain actions at certain points in a game.
