I didn't think Barcelona would perform like this after the incredible Borussia Dortmund game. I thought they would win the game with a lot of goals but they really struggled to score. The only goal Barcelona scored was an own goal. It doesn't matter, Barcelona won the three points and they still continue to lead. I think even a one-goal win is enough for the championship. I'm sure Barcelona was only focused on the three points, I don't think they were upset because they couldn't score many goals, so they got three points.
Just like I didn't expect Arsenal to perform like they did yesterday against Brentford in the English Premier League after their outstanding performance against Real Madrid last week, I also didn't expect Barcelona to struggle against against Leganes but then again, the players are humans and must have suffered fatigue for putting in their best against Borussia Dortmund last midweek. The important statistics in their game yesterday was to get a better scoreline which will guarantee 3 points and are the end, they got it and that's what I think that matters.
