De Zerbi got destroyed by Roma.
Wasn't he supposed to be the new Guardiola

I can understand if De Zerbi could be destroyed by AS Roma.
The quality of his squad isn't as well as the AS Roma squad quality. And De Zerbi may use the wrong tactic in the match against AS Roma.
De Zerbi manages an average team like Brighton, it is different with Guardiola was managing a big team like Barcelona.
Anyway, I don't think De Zerbi needs to be the next Guardiola.

Ac milan played openly, sometimes they were too busy attacking and were not ready when there was a counterattack. Ac milan has a big advantage in this match because they are playing at home and are also superior in number of players. The current score was 3-2 where Prague was able to reduce the deficit in the second half. I think Ac milan should be able to take advantage of the situation to continue scoring goals because in terms of play they are able to dominate it well.
I don't see they are playing too openly. They just forget to focus on their defense, they are too busy attacking.

It is funny that AC Milan conceded a goal again, it was already 2 conceded goals. Although they already scored 3 goals, it will be nothing if Prague scores again a goal. It can be 3 goals made by Prague if AC Milan defenders play carelessly.
