With 10 minutes to go, Barcelona still leads 1-0 against Benfica despite Pau Cubarsi being sent off in the 22nd minute.
Scoring the only goal (so far) and dominating in possession despite being down to ten men shows a difference in levels between those two teams.

I'm surprised to see no goals in PSG Vs Liverpool. I expected Liverpool to win, but if the game ends with a 0-0 draw, that's still favourable results for the Reds, as away goals no longer counts as a tie-breaker. So it will all be decided at Anfield next week.
