The match between Inter Milan and Atletico Madrid is gonna be decided by how Atletico Madrid wake up today, if they wake up in a good mood, we can expect a surprise on the Giussepe Meazza and see a win for the spaniard team, if they dont wake up in a good mood we can expect a dominan Inter and a win like 1 or two null for them.
Actually, this is a difficult match even though we know Intermilan are favorites to win, but Atletico Madrid certainly won't give Inter Milan a win that easily because they can make things difficult during the match, Atletico Madrid often make surprises, for that I won't underestimate them though playing as a guest, I bet on Inter Milan but I don't want to say that Atletico Madrid is easy to beat, my prediction is maybe Inter Milan will win narrowly because Atletico Madrid will provide quite tough resistance today.
Although in these matches we cannot guarantee any team winning because both sides are going to be consistent to win the game, I think Inter Milan is the favorite in these games. Even though I believe what you said that Athletico Madrid makes surprises against big teams, I think in these games Inter Milan is going to win because another thing that will make Inter Milan stronger is that they are going to play at home. At this point, I will say they are stronger than Athletico Madrid and are still going to play at home, so I believe Athletico Madrid are going to find it difficult to win the game.
There's no need to see whether Atletico Madrid is in good shape or not, but so far they have always given surprises when playing against strong and great clubs. For example, against Madrid, sometimes they make things difficult, that's why Inter Milan still have to be aware of that and be careful when playing. Simone Inzaghi must use a special strategy to face Simeone's men today, it is likely that this match will show their best game. I definitely won't miss this match to watch because I bet on Inter Milan.
Observing how good a team is matters because that is what will determine the team that is going to win, so if Athletico Madrid is not in good shape, it matters, and we need to see that, so you saying that there's no need to see whether a team is in good shape I disagree with that small moreover with Athletico Madrid make things difficult for Real Madrid I believe that is what Inter Milan are going to put in mind and dominate to the match they wont allow Atletico to the same thing to them so let see how they will do in the match.
