Underestimating the opponent they will face is a big mistake that Inter made, I think Simone Inzaghi will not do that because he has seen how his opponent played when they held Real Madrid to a draw. It's true, Atletico Madrid is not a new team in the UCL, this team has reached the final several times. Inter must remain focused on its goals, whoever the opponent they face must be considered a strong team to motivate the players to perform better. The coach's ingenuity in formulating strategies will be determined in this match, Inter must remain focused and careful with Atletico fast and sharp counter attacks.
At some point I got confused with what exactly you are really getting at because I'm seeing three different teams been mentioned with almost what seem like same reference especially talking about Atletico getting to the finals severally and inter staying focused
Nevertheless for the much I know inter has gotten to UCL finals more but then if atletico would want to get to the finals at this point then it's definitely not a bad one as it's been a long while since the got to the finals of the UCL but they have to first beat inter Milan to be able to get to the semi finals before proceeding to the finals. According to history inter Milan has participated in five UCL finals meanwhile Atletico has just three so imter is more experienced in the UCL than Atletico so I don't doubt the chances of inter winning.
