Porto can play attacking, have nothing to lose, but Chelsea loves to play so much when they are given space to counterattack. although I wouldn't be surprised if Chelsea has more ball control. nevertheless, Chelsea has a very good lineup of players, perhaps in the next seasons they will be even stronger.
Bayern - PSG. last year's finalists, who are still fine. I do not think that a very strong failure of PSG is possible, unless something extraordinary happens, for example, the removal of a PSG player in the first half.
