Yes, it was a suffocating defeat, Inter had several challenges that they really missed. And in the end, he failed in the penalty shootouts. And it makes for a great lesson for them. And at least, they have 1 title which is definitely the most prestigious in the Italian league, because they will definitely take the Schudetto this season. It's just a matter of time, the points are so far away from the other clubs, and there are only a few more matches left this season. So, it is certain that Inter will take over the Serie A trophy from Napoli, the champion last season.
The level of competition in the UCL is different from Serie A. Even though Serie A is one of Europe's top leagues, the teams in the Champions League are elite teams from other top European leagues. Inter Milan has an advantage because they can focus on the UCL. But Inter Milan was unlucky because they lost on penalties to Athletico. Winning 14 points has secured their position in first place. I think Milanese can throw a championship party for Inter Milan. 99% they will be champions. No doubt.
