Yes, Inter Milan is in form lately, but when it comes to their game against Atlético Madrid , I don't think they will find this game easy to win because, I have known Atlético Madrid as a stubborn team when it comes to anything pertaining the Champions League games, despite that they have not been consistent with their performance in a couple of games now but ATM got good experience to play and even deny any team the opportunity to win regardless of how form the opponent team is at the time of meeting.
Atletico Madrid is very resistive with their defense line and that will be what inter Milan will have to battle to be able to get a win in that game and this will mean they will have to put in some extra effort to make sure they are able to break the defense of Atletico .
Looking at inter Milans performance again Juventus, you will understand that they were and are still in a very good form because they really didn't get it easy with Juventus and so with even if Atletico will definitely prove so hard I still believe they will be able to get around atletico and be able to see how well they can perform to getting a win because it's really important for them to get a win which will means them still staying strong in the champions league this season and getting to the finals just like they did last season.
I am unable to predict the outcome of the match between Atletico Madrid and Inter Milan because both teams are performing well. While Atletico Madrid may not play well in the Liga, they will undoubtedly play well when it is the champion league, and Inter Milan has also played well since the start of the season, so they will also be able to defeat Atletico Madrid. The only strategy that Inter Milan will employ to overcome Atletico Madrid is their fast-paced style of play. They also have one of the best strikers in the league, and the defensive players of Atletico Madrid will prevent him from scoring goals in the manner that he did in the serie A league.
Even though I don't have a favourite team, I think Atletico Madrid should win because, in the previous season, they were unable to advance past the semifinals, and Inter Milan reached the championship round, where they proceeded and played as if they were playing without legs. To be honest, Inter Milan had no idea how to handle a champion league final match. If Atletico Madrid or Real Madrid were to face Manchester City in the final, it would be a difficult match.
I agree with you, Atletico and Inter are equal teams. Both teams are fighting for leadership in their respective championships at the moment, both teams attack a lot and show good football. Now to predict the outcome of the match between these clubs is virtually impossible. By the way, today there will be a match of the Spanish Cup and Atletico will play in this match. I think after this game we will be able to say more confidently in what condition Atletico is in now and make a prediction for the Champions League match.
