Now there is no reason for Inter Milan not to focus on Serie A, they have already been eliminated in the Champions League.
Inter Milan have nothing to worry in Serie A because they have 16 points more than AC Milan and Serie A has only 10 matches. Inter Milan need to lose 5 matches and has one draw while AC Milan must have perfect results in last 10 matches to get Scudetto from Inter Milan.
This will never happen even Inter Milan will feel disappointed after a shocked defeat in Champions League. They soon will return to a good mood and complete their job in Serie A.
Inter Milan has nothing to regret, because in my opinion this is inseparable from Atletico Madrid's great luck. Moreover, in the penalty shootout round I prefer to say it was a round of luck because the chances of each team were 50/50. No one can predict who will win in the penalty shootout. So Inter Milan must immediately forget their defeat in the Champions League and look ahead to their match in Serie A. At least they are on the last step to win the trophy this season.
Inter Milan from their coach to players have to regret a lot because of many wasted opportunities. If they can score only one more goal from many missed opportunities, they would have been the winner even without penalty shootout.
I am sure they are regretful about that and Marcus Thuram, Lautaro Martinez will feel a little bit individual responsibility too.
Yes, if they continue to be lost in disappointment, of course it will make them play without focusing on the domestic league which will make them inconsistent again, because even though their point difference is difficult to catch, if Inter Milan suffers a losing streak in the remaining matches because they are not too focused, of course will be detrimental to them, what is clear is that Inter Milan must be able to accept any result in the UCL, even though they lost to Atletico Madrid, they must learn from that defeat to become a better club in the future in the UCL next season.
I think there is too much disappointment, some supporters are making insinuations, such as on social media, because of Martinez's failure, but all supporters, don't look at one mistake, but look at the struggles they have faced up to this point, it is not easy to consistently maintain performance and stamina playing in the domestic league and also in UCL, because if it is not maintained, all the great players will definitely experience fatigue due to the busy schedule, Inter Milan must be more focused until the end of the season and win the Italian league title this season.
