Barcelona are unlikely to lose against Benfica . Barcelona won the away match by a narrow  margin of 1-0. However, in just 22 minutes, the referee showed Pau Cubarsi a red card. It was very difficult to win the match with 10 players. However due to Hansi flick's excellent match strategy, Barcelona was able to secure the victory until the end. Although Barcelona's overall performance was a bit slow in the first leg match.

However, in today's match, I think Barcelona will play attacking from the beginning of the match. barcelona will want to win the home match  by a large margin. benfica is not a very strong opponent for Barcelona. I  guess Barcelona will want to win this match by at least 2 goals...
