Hard to guess which club between Madrid or PSG will advance to the final, but i think i'll pick PSG. My reason is that they played more collectively, and often beat their opponent with huge score. however, still predict there will be an intense game with very minimal score.
If we compare the statistics and previous performances we can say that PSG is more prepared and has a higher chance of reaching the final. PSG under Enrique has become a monster besides the chemistry between the players is very good. On the other hand this is Madrid first season with their new coach so there are still shortcomings in the team but considering they are Real Madrid, I don't think they will be easily defeated. Madrid always performs well in the semifinals.
