It's still too early, the transfer market even isn't over yet and the strong candidate teams to win the Champions League haven't even introduce their main squad for next season. The issue of transfers for top players is still blowing like Victor Osimhen, Kylian Mbappe who is link with Madrid, Harry Kane with Bayern Munich, Manchester City will face obstacles if some of these issues are realize before the season starts, especially Real Madrid and Bayern Munich is the candidates strong at UCL.
Even the opening match has not happened yet. People were speculating if Manchester City could take the trophy again.. It's caused by city is still very strong at this moment.
Even though some key players were leaving from the club like gundogan and mahrez or even walker. The club has recruited new talented players who are as skilled as the departing veterans. I see no problem when people are talking about which club that potentially win UCL.
The transfer season has been making the situation in the club become dynamic and that's unpredictable. There will be so many changes for the upcoming seasons, especially for manchester city.
