I believe either Manchester City, Liverpool or Napoli will win this season because they're very hungry to get this trophy.
Manchester city and Liverpool are definitely potential winners of the tournament because their side are playing very good football and have the squad to win other strong contenders in the tournament but what's Napoli doing in that statement. They have no chance of winning the champions league even with Osimhen been on the form. I'm even suspecting him leaving the club this January as he has many interest all over Europe and he better take his chances now and go to a more profile club.
Fans will be counting on Messi to bring same spirit from the world cup to the champions league and help PSG win the champions League.
Was Messi the best player at the world cup? He wasn't, he just scored cheap penalties and was favored all through the world cup just because the officials wanted him to win and it was obvious. I don't think they'll favor him in the champions league. PSG aren't winning the champions league until they let go of signing superstar and focus on signing players that still have alot to prove and put all on the line on the field.
With the Haaland project. Manchester City is one of the clubs that is frightening for their opponents, especially if The Citizen brings in several players this January. for sure, will add strength to their squad later. but not for Liverpool this year, I'm quite optimistic that Klopp will eventually be able to lead his squad to finish in the top four in the domestic league. however, their consistency in carrying out their matches has not proven to be stable. What's more, Liverpool have a very tough opponent, apart from their opponents having big names, they also have a winning mentality that the current candidates don't have, namely, Man City and PSG.
Speaking of Napoli, there are many rumors surrounding Victor Osimhen's departure this January. but I doubt it, although rumor has it that Nopoli is in need of a sizable financial fund. chances are, Osimhen will be released by Napoli in the next summer window.
as for Messi, everyone has the right to express his opinion including you. but for sure, he has ensured that he and his country won the world cup. for the Champions League, however, Messi is one of the important players to realize PSG's dream of winning the champions league trophy for the first time. even then, if PSG manages to become a finalist in this competition.
