but I instead think that Milan vs Liverpool will be less interesting than Manchester City against Inter due to the two teams wanting a rematch in every way so it won't be a static match with a foregone conclusion, we'll see anyway
The thing is that this match is iconic, it reminds us of that final when City won their UCL for the first time and it was against Inter where I remember that Lukaku eventually missed all the opportunities, that was something impressive, seeing Pipo Inzhagi's face was something impressive, I couldn't believe it, however I think it's a good, interesting revenge match and they can make the difference this time, I see that City is very good, Inter too, but I think that if both play very well Inter can take the victory, since they are playing with that feeling of what could not be done before.
For me both are interesting matches, the difference is because this will be the meeting of the two teams that were in the final in the previous 2 seasons, exactly as you said. Football fans look more in that direction, but if we look from all directions then both are equally interesting matches because they will bring together two big teams from different leagues. Our memories usually stick to certain moments, so this is one of the reasons. If the situation was different, like AC Milan and Liverpool who were in the Champions League final in the previous season, then a narrative like this would also be heard that some people say AC Milan vs Liverpool is a more interesting match than Inter Milan vs Manchester City.
