Yes, winning UCL back to back is a very unique and rare thing. Let me put it this way, for the past 30+ years, the only team that won back to back was Real Madrid, who did win 3 times in a row, but that is it, nobody else had 2 titles in a row. When you consider that, do you really think no team was good enough to win? Of course there were teams that were better than others and still lost.
So because we have a historical data that shows that for the past 30+ years only one team did it once, I doubt PSG will be able to replicate that, and most likely it would be like the other 90%+ of the finals where they will not win. Lets see if we are right or not, but it is obvious that we are going to see these things change, and maybe it would make more sense for them to get a better result.
Paris Saint-Germain will never be determined to win games if Luis Enrique didn't put some arrangement together, we know how important this is for the players and the fans, they toiled season by season to accomplish a major trophy, nothing happen until the presence of Luis Enrique. Common guys, we're talking about Paris Saint-Germain here and winning the UEFA Champions League back to back? I don't think it's possible but Les Parisiens to carry out this crucial work, there have been some up and down movement in the club lately after losing to Chelsea in the club world cup final. This is an event that wouldn't happen if we've watch Real Madrid in this position. When you lift UCL trophy, the best will always be there to make things happen.
