Atalanta are not as strong as Liverpool, so I still think they will share the points with Real Madrid. I don’t mean to belittle Atalanta impressive record in the Champions League this season, and I don’t want to ignore the half-dozen injuries to Ancelotti key players, but I am trying to see Real Madrid as a team with a number of quality rotation options. Atalanta failed to score against Arsenal and Celtic, which is something to consider. Besides, Ancelotti is no stranger to the Serie A side, and he has plenty of experience of facing them. When Real Madrid are under pressure, they can almost always turn things around, especially in the Champions League.
I agree with you, without closing off Atalanta's chances, with respect to how Madrid has performed in the UCL it's obvious that things haven't gone very well for them, in fact for me Mbappé shouldn't start him anymore, it's better for him to be substituted, thanks to him, Vinicius doesn't play in his usual position, they make Bellingam drop back as if he were a recovering midfielder, I see him more as a left midfielder than an attacker, so that type of formation is useless for me, it's too much of a sacrifice just for Mbappé to feel comfortable, this is the type of problem that I didn't want to arise at Madrid.
