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. :
Excuses. The premier league is just not as difficult as people mae it seem. Everybody said Roma didn't stand a chance against Brighton. I remember saying here that both teams stand a chance to win. Even I didn't expect it to be so easy for Roma.
This further proves the misconception that the premier league is harder than other leagues.
Aston Villa couldn't score against struggling Ajax and West Ham too couldn't get a goal against Freiburg. But these are teams from the league that premier league fans say isn't good enough. Although Aston Villa and West Ham still have a slim chance to qualify, I think this is the end of Brighton's journey.
De Zerbi can't be the next Pep Guardiola. The next Pep Guardiola shouldn't be conceding 4 goals against Roma in the knockout stage of a European competition.
Arsenal too is another English team that should be careful in Europe. The fact that they're tearing things up in England doesn't mean they'll do the same in Europe. If they get overconfident Porto might just surprise them.
