I do not underestimate them, but I really doubt if they can win that Champions League back to back, has anyone done that asides Real Madrid?
Bayern Munich, Barcelona, Manchester United though, they're yet to make quality additions to the squad. Even Inter Milan can come back next season to win, they did great just that they didn't have that killer player to open Manchester Citys defense. But anyways, we still have two months until the next Champions League kick's off.
every season has its own challenges for the teams that are fighting in the champions league, and i'm sure in the next UCL season we will see again how man city fights hard to be able to win the UCL trophy, to be honest in the final match when facing inter, i saw man city play sangta is not good, they are quite lucky because inter failed to score. what I will pay attention to in the next season is man utd and real madrid, these two teams will definitely not give up again and we will see how they fight tooth and nail to win the UCL trophy from man city.
