Slot faces the unenviable task of replacing popular and veteran manager Jurgen Klopp.
Speaking to The Telegraph, Pusic said: You will not see him running to the stands and jumping and that kind of thing. He's switched on, very much focused on the details.
He has a lot of deep thoughts about the game, about the development of the game and is an amazing coach he showed that already in Holland, but not only in Holland, also in the games we played in the Europa League and the Champions League and also in the Conference League.
It doesn't mean if you're not running in front of the stands that you're not passionate enough; it's not a good comparison. Nobody's the same. Every person, every coach is unique in his own way.
Arne is calmer, he has of course a lot of passion for the game and he always has nice interactions with the people. He has a lot of feeling for good atmospheres in stadiums and appreciates the fans a lot. He finds it very important to cherish the club and the team."
