It is impossible to make a definite prediction about the Champions League. The Champions League is very competitive and unpredictable. We considered Real Madrid and Liverpool to be the favorites for the Champions League title this season. But we did not see a good performance from these teams in the knockout round.
Then we considered Barcelona and Arsenal to be the favorites for the title. But both teams were eliminated in the semi-finals. Unexpectedly, PSG played well in every match of the knockout round and won the Champions League title for the first time.
Since the beginning of this season, many people have had hope for Real Madrid and Liverpool that they will be the favorites to win the Champions League this season. When the season was about to end, everybody realized that their performances were not up to considering them as teams to dominate the league, and even Arsenal, which I was having hope for after they escaped from the knockout round, was later eliminated by PSG. Since that time, in the semi-final, I know that they are still in good form.
Next season, Madrid, Barcelona, City, Liverpool, PSG and Arsenal are all trying to increase their strength. Their target is definitely the Champions League title. So it is not possible to make a prediction right now about which team will do well next season.
To be honest, next season they will be a tough competition in the Champions League. Because those 6 teams that you mentioned earlier will make the league a very tough one, as most teams are targeting signing more players so that the team can be well standard.
