Atalanta must improve, even though they performed quite well in the UEL, they lost surprisingly against Torino. 3 goals from Torino making Atalanta failed to overtake Napoli positions in standing, who also lost by the same score. Next, Atalanta will meet Milan, a team that is currently also inconsistent. In this match, Atalanta must maximize all opportunities to score goals. For AC Milan this is an important match that must be won. Because Milan still has a chance to become Serie A champions this season, this win to keep the points different to Inter Milan still possible to be shifted.
Yes, many football observers are disappointed with the results obtained by Atalanta, what you said is true, if they don't change for the next match, of course it will really affect their future results in the standings, because next week they will face a team whose game is improving last week, of course. AC Milan just wants to steal points at their opponent's home ground to reduce their point difference in the standings. If Juventus' final result is a draw against Napoli and AC Milan wins, their point difference will only be 1 point.
