It is always difficult to determine who will win the Champions League title, especially when the season has not started. Manchester City certainly have a chance to repeat their success, but to defend the Champions League title then I think it is the most difficult challenge for any coach. Pep Guardiola is expected to keep his chances good, but all the teams that will be competing in the Champions League will also be pushing for the title.
Yep, Barcelona is the biggest contender in this league, Bayern Munich can be a strong contender as long as they can sign Harry Kane.
For Real Madrid, PSG, Inter, Milan, Arsenal etc, they're still in development phase to find their best eleven players.
Surely Manchester City is still look as the strongest club, but they're not yet in the same level like Real Madrid in 2015-2017 seasons where no one can compete against them.
I also think so, Barcelona have found players who are ready to challenge other favorite clubs like Manchester City who successfully won the UCL title last season. Bayern Munich who are in a transitional period with Tuchel will try to show something extraordinary in the UCL this season, they are trying to find a new striker after Mane's departure, Harry Kane is in their hunt.
Arsenal and Manchester United are ready to make a new journey this season, they have made a major overhaul in order to provide competition in this most prestigious championship. Especially for Real Madrid, the club that has won the most UCL trophies, is looking for a new striker after Benzema left for the Arab League. Mbappe, who is often rumored to be most wanted by Real Madrid, has not been inaugurated to date. It seems that Real Madrid needs to find another target to complete their squad to take care of the opportunities that were delayed last season.
I have strong belief in Barca this upcoming season and I know since they didn't qualify for the champions league last season, Xavi will want to use this season to show the world what he gat in UCL. Barca has strong game plan and strong players well prepared for the tournament.
Although the league hasn't started and we can't tell about the performance of any club presently but I strongly believe that there is not for M.city this season. Bayern can do better if they get a good striker to replace Lewandoski because I don't know what is their deal outcome with Harry Kane. Manchester United might still surprise the world too but let's see if it will be possible for them.
