It seems, it will be difficult for Barcelona in this match, playing away and in the 22nd minute Barcelona defender Cubarsi got a red card. But even so, it seems Benfica also still has enough difficulty to score their first goal in the first half after Barcelona played with only 10 players. But yes, in the second half it will be very possible for Benfica to score a goal and beat Barcelona in this first leg. But, if Benfica fails to beat Barcelona and the match ends in a draw, then the result will still ensure Barcelona still has a good chance in the second leg to qualify for the quarter-finals. But so far until the 43th minute, Barcelona is still leading for ball possession, and that is a good effort to not give Benfica a chance to score a goal.
A red card does not really affect a strong team but it does for those teams are not strong enough to defend their side. When a red card is given to a player, the remaining players have to re-strategize in the field to defend themselves and strike more to scare the opponent and with that fear, the side with 10 players can score again. Barca has not to worry because of a red card to a player instead focus and strike more. Barcelona now is leading with 1 - 0. Raphinha scored the goal at the 61 minutes in the second half, though Benfica tackling Barcelona but Barca is also resisting their attacks. From my own view, Barcelona will win the match.Barcelona has really earn my trust tonight because how they were able to win with a red card all the way from first half needs to be studied, it was even as if when they got the red card they activated their energy and i like how they defended with all their strength till Raphinha found the back of the net. If i was told that Barcelona could win Benfica even with a red card i won't believe. So if Barcelona had not gotten a red card who knows if they would have scored more goals. I'm so happy for Barcelona because since they secured a win from away, it won't be difficult for them again when they meet in their own ground.
The match is almost getting to an end, and Liverpool is still yet to score a goal. I will not conclude at this point, as they still have more than 10 minutes to go. If not, PSG is really making it difficult for Liverpool to score a goal, seriously, so let’s see how the match is going to end. Maybe Liverpool will be able to clear the zero even if it’s with one goal. It’s football, and anything can happen even if it remains 1 minute.
Liverpool has just scored 1 goal. It is quite surprising that Liverpool only has a very small chance to score but they finally succeed scoring goals. So far, Liverpool only has 2 total shots. Meanwhile PSG has 27 total shots, 10 shots on target. I totally can't believe that they failed to score a single goal. There is a big problem with PSG attackers today. They have a very lack accuracy. 
Honestly, with how PSG dominated Liverpool, i didn't know that Liverpool ended up winning after all the pressure PSG gave to them to the extent of firing 10 attempts on target but could not score anyone but Liverpool just have one attempt and they utilized it perfectly and won. The accuracy of PSG's attackers is zero, they should be targeted when they are facing a bigger opponents.
