Maybe some of the factors that made Barcelona look so weak in their last match were due to fatigue which caused the team's performance to decline slightly. Facing Atletico Madrid will certainly be a little more difficult without Lamine Yamal and may force Barcelona to appear more careful. Atletico Madrid are on a positive trend so facing them in their current condition will be a big challenge. Barcelona must win the match if they want to stay in first place in the standings, but if you look at the opportunities, maybe a draw is much more likely to happen because Atletico Madrid are also in a fairly favorable condition.
Barcelona attacked the whole match, they played the same as in their previous matches, just Lagenes was lucky in this match to play very well in defense. Sometimes it happens, Barcelona spent the whole match in attacks, but unfortunately they could not even equalize the score, I think if these teams played each other a few more times, Leganes would not have been able to keep their goal without a goal, but on this day they were lucky, and they were able to score a quick goal, it was just an unlucky day for Barcelona.
