Such an assumption could be true even though the assessment is only from the two matches at the start of this season, because overall in the first two matches for this season Roma really looks difficult to get a win even with opponents who are not stronger than them. Meanwhile, Milan has shown very different things at the start of this season so it can be said that Milan does have slightly more strength than Roma this season. And what can be seen is that AS Roma really needs strikers this season because Roma is still very short of players in the attack line this season.
Roma started last season with the best defensive game and maybe that's why they had the best results. At this time, they concede more, but they don’t play badly in the attack either, even in the match with Verona they hit a lot on goal but scored only one goal. It's still too early to say what it is, and the next match with Milan will help to understand what Roma are capable of and how Milan are stronger than them.
AC Milan preparation this season is better than AS Roma, it is evident that Milan first two matches managed to win full points. Slightly different from AS Roma, they had to accept defeat and draw in the first two matches. Playing at home is indeed beneficial for Jose Mourinho's squad, but we cannot close our eyes that Milan has a squad above Roma this season.
The most reasonable prediction for this match will end in a draw, if Mourinho uses a defensive game. However, AC Milan chances of bringing home the three points are greater, because their performance is still very good.
