I do believe that City will probably win, but even with that idea I do not think that PSG will be an easy target. However the hardest part is, PSG and Bayern played and people called it an early finals because both teams were good enough to beat most teams except maybe City, and now City and PSG will be playing as well, that is another early final as well if you ask me. Whoever ends up winning in the City-PSG game will probably be the champions if you ask me.
Manchester City and PSG have the same level, from quality of their players and their experience in Champions League. The coach can be different with Pep Guardiola and Mauricio Pochettino but Pep has never shown his best in Champions League after he left Barcelona.
He made some few strange decisions in important matches and after his golden time in Barcelona, he has yet gotten success in any other clubs. If Pep won't make crazy invention with his squad decision, Manchester City can win and get their first final match. Even so, two teams have 50 - 50 chance.
If Pep makes strange things, PSG are strong and wise enough to beat Man City down.
Sure madrid-chelsea is a good matchup, I assume Madrid will probably win that one and will go to finals and a team that has been to finals so many times (and won so many times recently with some of those players still in the team) will have an amazing experience and will probably be more calm, whereas City could have some panic, whereas PSG may have even more because they missed it last year. Even with all that in mind, I say whoever wins PSG-City will be the winner.
In this pair, my choice will go to Real Madrid with Zidane. Chelsea got some good results with Tuchel but his defense system still have problems and it can be broken by Zidane and Real Madrid. If you see the ability to control matches, tactics when they play against Liverpool, Chelsea will get big troubles.
