I also thought the same. Atalanta couldn't find the back of the net because Inter defense was very strong. However, after the first goal in the second half, that was when I started losing hope in Atalanta because Inter was able to spot out their weak points and took advantage of it. Currently, I don't think there's much hope for Atalanta to win Scudetto this season, because Inter wouldn't let that happen.
Will Atalanta win the Scudetto? Not at all; Inter Milan will not allow that to happen this season, and I am confident that Inter will do all it takes to win the league title again. I wasn't expecting Atalanta to do better against Inter Milan; just because Atalanta defeated Juventus 4-0 away doesn't mean they can win Inter Milan because Juventus has turned into an average club this season. I predicted that Inter was going to win, and the match turned out as expected.
Meanwhile, Inter will face Udinese and it is predicted that Inter will win this match. If that happens, the points difference will be 6 points and this will make it even more difficult for Napoli to win the title this season.
Inter is the favorite to win the next match against Udinese, but I wouldn't be surprised if the match ends in a draw because Udinese has been stubborn in playing against big clubs this season. Inter, on the other hand, defeated Atalanta, which is fighting for the league title, while Udinese lost their last match against a weak club. Moreover, Inter Milan must play as if it is their last match against Udinese to win the league title.
