Probably, if everything were so simple, the bookmakers would not give such generous odds - 1.83, does this not bother you?
It is clear that Milan is a big favorite (1.53 according to bookmakers) if we talk about the total result of the two games, but I am not sure that the victory will be easy. By the way, the chances for BTTS Yes are very interesting - 2.04. It seems to me that, taking into account the imperfect defense and good attack of both teams, the coefficient compensates for the risk.
Yep, both of the teams are sharp in attacking line, so each of them should able to score a goal. We can't really predict the result, there's a chance it will end in draw, just like in Champions League match yesterday where the two matches were draw.
Just checked the statistics. It turns out that Milan scored goals in all of the last 10 games, and Roma scored goals in 8 of the last 10 games. But judging by the odds on BTTS, bookmakers expect Milan to win dry. Questionable expectations - if you look at the Serie A standings, you can see that Milan is the worst in the top 4 in terms of the number of goals conceded and they concede more than one goal per game on average.
