For a club that kicked out Liverpool, Man city, Anston Villa and Arsenal, dismantling Inter to a 5:0 defeat wasn't a surprise. They were outstanding including Desire Doue in the match doing his best as a young star. Inter couldn't stand the playing strategy of PSG just as the top English teams weren't able to decode it. The Perisians only got better unannounced.
The final match between PSG and Inter Milan was indeed a surprise to many people, especially since the score was also unusual, namely 5:0. It was something that was unimaginable before the match and even the finals that have occurred in the Champions League have never had a score that much. So PSG cannot be understood by all the teams that have faced them last season, namely the teams you mentioned, and I hope PSG can continue like that next season with some improvements because overall PSG's performance is clearly quite extraordinary when compared to other teams.
