The UEFA Champions League title is only among two promising clubs, Real Madrid and Paris Saint-Germain, but when it comes to their opponents, they're not regard small because they developed important winnings. PSG headcoach, Luis Enrique is doing a great job for Les Parisiens this season. In his first season incharge of Paris Saint-Germain, he already giving us signs about his competent actions, he's taking Paris Saint-Germain to the final right away. A tough fight for both elite teams.
Real Madrid and PSG are favorite teams for the final matches but they have to solve two opponents in their semi final matches. Their opponents are Bayern Munich (for Real Madrid) and Dortmund (for PSG). From history it seems Real Madrid have a little advantage against Bayern Munich but difference is not too big and clear.
With PSG, two previous matches in this season are big red flags for them before two semi final matches. PSG need to be careful if they don't want to lose one or two more matches under Dortmund in this season. Two previous matches in early of season, don't show that PSG are actually stronger than Dortmund.
It seems you were underestimating other team like dortmund and bayern munich, these two bundesliga teams can be the biggest threats to get the UCL trophy this season. Bayern's performance has been so underperform in bundesliga but the club is showing it can go to the semi final.
Tuchel is a genius in tactics and he can help Bayern Munich to cope with Real Madrid and Ancelotti in semi final matches. No guarantee that either Real Madrid or Bayern Munich will surely win semi finals and reach to the final match.
