Of course, next season Champions League will different from this season and we will definitely see good performances from clubs that were unable to reach the semifinals. Clubs that performed pretty good this season might not be in their peak form next season. Changes is always constant and we don't know what next season will be like to most of these big clubs.
Every season of the Champions League is very competitive. Was this season less competitive? The PSG vs Arsenal match was very competitive. Both teams had a chance to win. Also, in the Barcelona vs Inter Milan match, we saw an incredible result. Both teams played great and were able to score a lot of goals.
Only the final match in this year's Champions League was one-sided. Also, every match in the knockout round was exciting. None of us thought that Inter Milan would play so badly in the final match. Inter Milan conceded 5 goals and did not score a single goal. I have never seen such a one-sided final in the Champions League before.
But you are right that the Champions League will be more competitive next season. Because Madrid, Munich, Liverpool, City and Barcelona are all trying to strengthen their squads even more.
