In as much as it is too early to predict which club that'll win the UEFA Champions League competition this season, I think it is also worthy to note that not this season's Champions League competition will be different from that of last season and I don't expect Manchester City to breeze past every club they'll be meeting this season like the did in the last campaign.
Real Madrid is a stronger team now than last season and that's because of the quality that was added to the side by the signing of Jude Bellingham. Bayern Munich in the other hand has also recruited Harry Kane to their side meaning that they now have someone who can play the role of Robert Lewandowski in the club once more. it'll be a keenly contested one this season
IMO, I can't speculate too far because I can't confirm the strength and consistency map of each club that will take part in this competition. after all, the domestic league has just started, we can't even be sure of the consistency of each team mentioned in this post. Madrid had two good matches, but they have yet to find a comparable opponent to measure how strong the team is and how consistent the new arrivals are.
City, remains the strongest competitor for the opponents they will meet in this competition later. even though De Bruyne has been injured, they still have a substitute as another option. Bayern, now has a striker who can be counted on as a goal scorer. Tuchel will focus on his team's squad, to win various trophies including the Champions League competition.
Barcelona, will try to be different with some of the new arrivals and at the same time their young players. their goal, to go as far as they can go. Seria A team, I don't know but they also have to be considered. it could be, if Napoli will appear far more competitive even though several of its players left in this summer's transfer window. likewise with Milan, Inter and others.
and yep, don't underestimate the several teams that have just returned to competing in this league. Arsenal and Manchester United will probably be able to tackle the more favored teams. Newcastle is no exception, Edie Howe's squad will participate in the competition to achieve the best results in this competition. well, I hope that the Champions League this time will offer and present exciting matches than in the previous competition.
