Having this type of win can definitely mean only good things for them. Looking for the current situation, they can win the league title, they can win the fa cup and they can win the UCL this season.
Pep definitely built a team that is better than any we have seen in a long time, maybe the only better team I can remember would be Real team that won 3 in a row and Barcelona team that did sextuple, those are the only other two teams I can remember that is better, that means when you consider 10-15 years in the past, that is just 1-2 seasons total with 1 team, that is an all time good team. I sense that they will get the league by the looks of it, and Inter should b easy, not saying they will get it neither, they may or they may not, but I can say that they have the biggest chance compared to Inter.
Manchester City's performance this season is very tremendous, I don't think there is any team that has performed better than them this season.
It is common knowledge that they are winning the FA Cup, Premier League, and UCL this season as a result of their superior play on the field.
Without a doubt, Manchester City is at its peak to win any matches that are on their way but their match against Inter won't be that easy for them to win. The head-to-head match between Inter and Manchester City shows that both teams have won against each other ones. It can be possible that Manchester City or Inter wins at the end of their meetings
