It is very difficult to maintain a high level of play over several seasons, after every peak there is a decline, and besides, other teams can be much stronger next season, until we know how Bayern will play, or what to expect from Real Madrid, Barcelona or other teams . Guardiola did everything right and City looked very good at the end of the season, but in previous seasons everything was not so perfect, so I'm not sure that things will turn out as well for City as they did this time.
Every season, of course, there are many surprises that we will see in the UCL, be it the defending champions defending the title or the challengers who are not seeded. This season belongs to Manchester city and it is not certain that they can maintain it next season even though they are still strong candidates. Competition will occur and this will be seen from the strong teams this season such as Bayern munich and Inter milan and even Ac milan. I think one of the things that amazed us this season was the decline in the performance of the Real Madrid team which other teams were able to take advantage of in winning the trophy.
Next season the team from the EPL will be enough to attract my attention, especially Manchester united. They were a big team in the previous era in UCL and this season they seem quite ready to give competition to other teams in the race for the ucl trophy. Erik ten hag will make a major overhaul in the transfer window to cement the team even stronger in the Champions League.
