The finals this year have never been tense or much less interesting. Even before the final it was clear who would win and given the way Inter played, especially from the experience of the game with Barcelona, it was clear that the score would be far from in their favour. In the end it turned out to be so and I personally was not surprised when the score was 2-0 or even 3-0, but when the score became 5-0 - it became clear to me that we are unlikely to see such a final in the near future, but it was not in a good way, because for Inter it was incredibly painful, but absolutely deserved with such a game
It wasn’t that clear I would say, most of us expected Inter Milan to pose such a challenge that would prove over whelming for PSG. Inter Milan have got history in the UCL and given the performance they had against Barcelona, kicking the giants out of the game, I hoped they would make a difficult win for PSG but nope, not even close to that. They served PSG the league trophy on a platter, making the finals a much less interesting watch. It didn’t look like a finals but they sure hated themselves to have made this history in the UCL.
I also think that Inter Milan will be a tough challenge for PSG because yes as you said that Inter really played well against Barcelona and the score of 4-3 produced in their last match was indeed proof that Inter Milan is a strong team that will make it difficult for PSG to beat them in the final match. and honestly I personally also thought that Barcelona would be PSG's opponent but of course Inter Milan proved that they are a strong team.
the point is in the Champions League last season of course it was unexpected that PSG would make a surprise by scoring many goals against Inter Milan and of course it was true that the final went as if it were not a final. but honestly with PSG's victory last season of course it made me happy too because PSG had never won the Champions League at that time. but now PSG has made history that they have succeeded in winning the Champions League.
of course for next season of course PSG will definitely be a tough rival for big teams like Real Madrid, Barcelona, Liverpool and others because until now PSG is still a really strong team.
