Milan win from Crvena zvezda is really predictable result because Milan is a big team in Europa so this match should be easy for them but a bit dissapoint because Milan unable to win with big scores from this match but indeed win is still win because basically Milan can successfully to earn 3 points from this match and currently Milan has 12 points from 6 matches and Milan performance in this competition is more stable compared to in Serie A because they can able to managed their consistency and for 2 upcoming matches Milan will fight against Girona and Dinamo Zagreb and if Milan can able to beat these teams probably they can improved their position on League phase and finish at top 8
Red Star's performance in the Champions League is indeed very bad so it makes sense if AC Milan can beat them, it doesn't matter how much score Milan created in this match a small difference is very meaningful for them to bring home 3 points currently their position in the standings is in 12th place with 4 consecutive wins that is an impressive result last season Milan could not qualify for the round of 16 and they had to go down to the Europa League, this season it seems the chance to qualify for the round of 16 is quite big if Milan can beat Girona and Dinamo Zagreb.
With only 1 win from 6 matches in the UCL this clearly shows how weak Red Star is, so it is very natural that Milan can to beat them, despite winning in that match but I saw Milan game was very ineffective and tended to struggle can to beat Red star, the victory further improved Milan position in the current standings especially with the remaining two matches that look easy and maybe can optimise later to win 3 points, Reportedly after Milan won over Red Star, Paulo Fonsesca actually argued with some of his main players , so I think when divisions occur in the team maybe it will affect their stability later in the remaining UCL matches this season.
