Atletico Madrid is an opponent that Inter Milan deserves to be wary of if you look at the strength that Atletico Madrid itself has this season. Meanwhile, Inter Milan is also very good this season so apart from being difficult to predict how their match will play, it is also quite possible that their match will be more intense because both of them are teams that both have good strengths this season. I also agree more with what you said that Simone Inzaghi must have special tactics when facing Atletico Madrid in the Champions League this season.
What should be their special tactics? By the way, Simeone also changed his tactics, now this is not the Atletico that is primarily worried about defense, they are also very active in attack. I would have said before that I expected boring positional play in this match, but now I think that both teams can score.
The first match will be at Joseppe Meazza, and it seems to me that this is in the hands of Atlético, they will try not to lose in this match and win the second match at home.
