We can say something similar this year. Inter was more focused on the Champions League title than the Italian league. They managed to eliminate Barcelona after two difficult matches and now they have advanced to the Champions League final. Paris Saint-Germain is their opponent and is very strong. A difficult match awaits them, if they become champions after 90 minutes, the failure in Italy will be covered up. It seems like a bad year for Inter at the moment, but if they win the Champions League, this can be reversed.
If Inter Milan succeeds in winning the Champions League title, all fans will forget about what happened when the team prioritized the Champion League title so that they ignored the Coppa Italy and Serie A, no one cares anymore about it because they have been lost in euphoria, but if Inter Milan fails, then the decision of the Inter Milan team will be ridiculed by many people, even their own fans.
Inter Milan's decision to focus so much on winning the Champion League title so that losing others is quite risky, but now they are almost successful, the final will face PSG which in terms of quality does not have a significant difference with Inter Milan, making the match much more fierce and the same opportunity for both teams to become champions, maybe in my opinion Inter Milan is just a little more about mentality because PSG has never won the Champion League title, that's what will make the Inter Milan players' confidence increase.
Inter are clearly aiming to win the Champions League, it is clear that they will do everything to win the Champions League, this will bring a cup that has been coveted in Italy for many years and as you say the fans will be happy to have won such an important tournament forgetting everything
