the Luis Enrique side are very young and ambitious from what I've seen them play, they are very good in using their wings, they kind of have similar character traits like Barcelona but are not that offensive attacking wise like Barcelona, however PSG have greater defence team than Barca so they could easily repel some of those attacking move inter Milan might have. But i believe inter Milan have stronger tactics and a unique pattern of play that can be defensive and offensive at the same time, that was why Barcelona could not keep them down even while Barca were scoring goals that could ordinarily demoralize them. For me i think PSG should be the one to find the format on how to stop inter Milan.
Yes, both teams have their own strengths, and we have seen how they have progressed from the League Phase to the final. There is no doubt that PSG plays more aggressively thanks to their young players, and they are supported by a strong defense. Meanwhile, Inter Milan with an average age of 29.5 players seems to rely more on experience, and that is why they were able to beat Barcelona. Both teams seem to have the same big chances, and I think it is possible that the winner will be determined through a penalty shootout.
