Looking at every team in the champion's league this season, the winner is going to be either Manchester city or Real Madrid because these are the two teams I still find best amongst others, I know there are other good tea s from other leagues but these two stands out and have always been, even their team currently have all the star players you can think of , that is why I believe strongly that between the both of them, one person will win the champions league.
What about Bayern Munich? Dortmund? Inter Milan? Milan? they are still strong candidates in the Champions League.
The Champions League is the most competitive league and there are many great competitors from other leagues so the winner of the title each season is sometimes difficult to predict although it does not rule out the possibility that Real Madrid is still the best club among other clubs looking at their history but I doubt Manchester City will get that title again even though he is still under Pep's tutelage.
Manchester City and Real Madrid do have quite prominent star players and I believe they have very impressive abilities but in the UCL they don't just rely on star players but also players with a strong mentality and doesn't that mean other clubs don't have star players? the fact that Inter Milan and Dortmund in the last 2 seasons have been able to reach the UCL final means they also have players who are quite reliable in competitive competition next season, no one knows what will happen.
