Milan lost when facing Dinamo Zagreb, how can you say that Milan won against that club in this 8th match, but even though Dinamo beat Milan, the club also could not secure itself in the play-off round, while Milan, even though they lost, remained in the play-off zone and will face clubs that entered the knockout round qualification to determine which clubs will advance to the last 16.
Loosing that game didn't do so much harm to Milan afterall, they are still able to maintain the 13th position in the table which has now got them to playing in the playoff and Dinamo Zagreb didn't get to qualify even for the play-off so that victory wasn't helpful enough to them. Basically it's didn't mean a lot to them, the ne t challenge now will be for Milan to try to make it to the knockout ad possibly get pass that stage.
