Well, this is a common occurrence which will certainly make it difficult for the team to be consistent. But about Milan, with so much pressure at the moment with a tough schedule, but Milan can still give good results even though they only get one point, but that is good enough for Milan at the moment. I hope Milan will continue like this and get the title again after a long period of difficult times.
Only in UCL they haven't performed well, haven't won in 4 matches while in the league they are quite good, it's difficult to be able to perform equally well in all competitions, only a few clubs can do that and that is supported by a good selection of players. Bad results in UCL should make Milan more focus on league.
This is the best decision I think because AC Milan currently has no hope even to be in 3rd position.
The last 2 matches in the group phase they had to play Athletico and Liverpool and in this match a draw should be the best because it is very difficult to win a match against 2 very big clubs.
On the other hand, instead of dividing the focus of the players, I think it would be wise for them to prioritize Serie A at the moment because their potential and performance is good enough to win the title this season.
