Don’t underestimate Atlético, Simione is trying to change the team, I see that he has moved away from the usual strategy when the team plays from defense, and perhaps he is right, because if we analyze the strongest teams that dominate now, they are attacking teams. But for Simione this is something new, which he probably still needs to learn. despite this, I believe that nothing is lost for Atletico yet, they have a chance to win against Inter, although I understand that this will definitely not be an easy match.
I usually think you are right that Simeone often has an ace up his sleeves, but I don't think this time it will play out well for them. Atletico Madrid had some unusual weaknesses for the whole season so far and I doubt that just now they will find the right way to deal with their issues against one of the strongest teams in Europe. Inter Milan is peaking in performance while Atletico Madrid wasn't able to find their peak performance ever this season. They had all these reversals after one good game. They did have some good games, but it when out of nowhere they lost points against a team that was at the bottom of the La Liga table.
It seems though as if Griezmann will be back in time, but whether he can show his best game after an injury is questionable. They will need a top top performance to win that game against Inter. A draw is not enough and that makes it so hard against Inter. They know how to approach that game for sure.
Atletico could not win against some of the weakest teams in the last couple of weeks and Inter is smelling blood here.
