You are right. I forgot about Atletico Madrid who also beat Real Madrid this season. And yes, this can indeed provide a big picture that Atletico Madrid cannot be underestimated. But I remain confident in the performance of Inter Milan, who are still the best team in Serie A this season. And as you said, Inter Milan has strong drive and motivation to reach the top of the UCL final again. But yeah, Inter Milan won't have an easy match. So losing or winning probably won't be a surprise for the Inter vs Atletico Madrid match.
Inter Milan facing Atletico Madrid is a very big match for them that they need to be careful if not they will be eliminated from the competition this early as compared to last season that they reached the final of the champions league competition. These two teams are really playing great football at the moment and their performances in this game will be the only reason that will give them their promotion to the next round of the league. The competition will only gets more competitive from this stage.
They must be aware of the consequences because after all, the Champions League is a place of champions just like the name of this competition so they must try to continue to be able to maintain their performance in this regard.
The consistency they have had until now is actually still very good for Inter and I personally feel for the first leg they will try their best to get a victory against Atletico.
Because, after all, this is an important step for them where the first leg of playing at home will certainly make their motivation even greater so that this is their chance to be able to get a victory in the first leg to be played.
On the other hand, Atletico are also still playing very well to this day and that could be a problem for Inter because however some Atletico players now especially Morata certainly know the style of play that Inter will do in the first leg this time.
