It's too early to call the shots of the likely winner of UCL trophy this season, until after the knockout stages before we can start predicting the likely winner of the trophy, this is football anything can happen, the so-called favorite teams might be knocked out by an underdog by creating an upset, Man City, Bayern Munich, PSG, Real Madrid can be defeated by any team, recall in the last UCL match between Man City and Borussia Dortmund it took the 80 minutes before the equalized and eventually won that match, Chelsea who used to be a very formidable team in UCL is struggling now however, they can still up their game and improve in their performance.
Early when predicting about who the winner of UEFA Champion League trophy in this season depending have pass two games only, actually with group stage have several bigger team can't predicting who will lead to 16 round exactly on group C where Bayern Munich, Inter and Barcelona have loss one team can't lead to next round. Several favorite team this season in Champion League still not get consistent performance from Barcelona, Inter Milan and Chelsea, I think several of us listed above team as favorite the winner of UEFA Champion League trophy.
I am waiting until group stage match finish favorite to be the winner in this season, I saw many favorite team faced difficult match in group stage and they have small percentage chance can lead to next round, between Barcelona and Inter Milan actually one of this team will left Champion League early but mid-week know who have bigger chance to win.
