Looking at the differences, AC Milan should be able to win this match. Even though they will play as the away team, they still look better than Lecce. But the problem is that they also sometimes play erratically, sometimes good and sometimes bad. Even when they play with a team that on paper has the same level or even better, they can play well, but on the contrary if the team they face is a team with a weaker status than them, sometimes they play badly so that they have to accept less than satisfactory results.
In terms of strength, AC Milan is indeed favored in the match later, but I think it is quite risky to bet on AC Milan's victory because their performance has been very inconsistent in the last few matches, so there is a possibility that Lecce can take advantage of AC Milan's slump, especially since Lecce will be playing at home.
This is a difficult match to predict because anything is possible and what is certain is that this match will be fierce for both teams.
