Tbh, every of this fixture is going to be tough, we could pick a couple of favorites on paper for now, by by then the game will be settled on the pitch and I'm expecting a couple of surprises, or to put in another way, upsets; last season City were eliminated by Lyon even when everyone expected Guardiola's men to go through, that result could give mochengladbach confidence in this game, I'll keep my fingers crossed till the games begin.
Barcelona vs PSG! That would really be a competition. Barcelona lost 4-0 in Paris a few years ago, and then won 6-1 at home before continuing. That was absurd.
I'm not expecting that crazy scoreline again, lol, and I think the both teams aren't even in form this season, things could obviously change before this game is played and I'll be hoping it does so we get a good match from both sides, imo, PSG go through.
