The odds are quite reasonable because the possibility of AC Milan winning this match is quite large, AC Milan must win and win this weekend if they don't want to get worse, after 2 previous results in Serie A and UCL AC Milan did not get satisfactory results so there is a possibility in the match Against VERona, the AC Milan team will be strong and that is quite possible after we see the quality of these two teams.
While Verona is in a slump right now, they didn't win in their last 2 matches, so AC Milan took advantage of this moment to win this weekend's match.
Considering how AC Milan dominated in the match with Dortmund and created many opportunities in middle of the week, Verona looks like not to be an opponent that can constrain attacking power of AC Milan. They will even face with bigger pressure from AC Milan as the host actually need three points after some bad matches in Serie A. AC Milan players hopefully learned something from their inaccurate shots in Champions League match with Dortmund.
They don't actually need to score many goals to beat Verona because opponent does not have good attacking ability. So one or two goals are enough for AC Milan to secure three points from Verona. I guess a best scoring goal for AC Milan from this match at home is 3 goals, not more but I don't see Verona will get one point from AC Milan at San Siro stadium.
