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.
Inter Milan is already experienced in this matter, but we also have to look at the strength of their second squad, maybe it will be a little balanced if they play with their main squad, I know that in the first leg of the meeting playing at Inter Milan's home ground, of course they have to be able to win the first match. them to be able to secure their position in the second leg match and get them through to the next round, we cannot see just by statistics how many times both of them reached the final.
For example, Manchester City, which rarely reaches the UCL final but was able to overcome Madrid and Munich last season, we have to look at the strength of their main squad, even though this is a match that is difficult to predict, I am sure they will show their best game to be able to qualify for the round. Next, I just think Atletico Madrid will make things difficult for Inter Milan and the result will be a draw in the first leg meeting, whether it's 1 - 1 or 2 - 2, both of them will definitely score in that meeting.
