I think Brighton can do a lot of damage to Rome because of his way of attack, Rome is weak in defense and Brighton has a very fast and powerfull attack, plus De Zerbi is Italian born and raised so he really know how Italian teams play.
But ROme still having some better players, lets see what win, stars or team work.
I think Brighton is luckier in this matchup in terms of some facts. De Zerbi knows Italian football well and is a quality coach. On the other hand, his experience is better than De Rossi. He also knows how to motivate his players. When we add the Premier League experience to this, a great team emerges. In my opinion, Rome's chances are very difficult. They must play without mistakes and take advantage of every opportunity.
Yes indeed, based on experience as a head coach, of course, De Zerbi has more or longer experience than De Rossi. So of course, De Zerbi has a better chance of being able to provide a good strategy for Brighton in the match against AS Roma later. But at least, considering that De Rossi has also so far been quite successful in providing good results for AS Roma, then yes, at least the match between Brighton v AS Roma will still be a difficult match for the two teams.
Therefore, at least I still think these two teams still have an equally good chance even though indeed, it still seems quite difficult for De Rossi to get good results in the Europa League. Because after all, in the previous match also the fact that AS Roma was not easy to beat Feyenoord and therefore, although Brighton and AS Roma have a good chance but it seems like Brighto will be the favorite team to win and to qualify for the next round.
