I think with or without the red card, Barcelona will still defeat them because the matching a revenge match for Barcelona following the 1-0 defeat Real Sociedad defeated Barcelona in their home in their Laliga first leg match; and this match is very important for Barcelona to win because it will give them the chance to lead the Laliga table ahead Atletico Madrid and Real Madrid and they finally lead with one point ahead of Atletico Madrid and three points above Real Madrid.
I agree with you. Barcelona has taken revenge for the previous defeat in this match. From the beginning of the match, we have seen that barcelona is very aggressive. At the moment , Barcelona players are very confident and they are in good form. The team has been able to play well in the last few matches . So Barcelona's only target against Real sociedad was to win . Even if defender ELustondo did not get a red card, we believe that Barcelna would have been able to secure 3 points from this match in any way.However , as a result of ELustondo's red card , Barcelona won by a large margin of 4-0.
Barcelona achieved what they set out to do to get the three points. The goal difference may have been high with Spanish defender Elustondo red carded and ten men playing, but the win was a result of a good performance from Barca. The absence of a player gave Barca an advantage but they were aggressive from the start, having almost 75 percent of the ball and having 33 shots on goal in the match 10 shots of which were on target.
Early in the match Real Sociedad had the ball in the Barca net but were caught offside for a slight error. I was disappointed at the time that Barcelona needed to keep their defensive players more active but the goal was disallowed. The rest of the match was mostly in Barcelona favor.
