Barcelona did not play like when they beat Atletico, the big names who strengthen Barcelona and have above average individual skills had difficulty breaking down the Las Palmas defense which played very well. One goal scored in this match was a very pleasant thing for Barcelona because they managed to secure second place while also cutting the gap with Real Madrid to 5 points.
A big team often have different mindset when the play against a weaker team compared to when they play against their rivals. This why, despite starting their current best lineup, they struggled to penetrate the defense of Las Palmas. It clearly seemed the performance didn't mirror the brilliance they displayed against Atletico Madrid. Scoring just one goal in the match must have brought a sense of relief for Barcelona, because it not only secured them second place but also narrowed the gap with Real Madrid.
Barcelona still need to improve the consistency of their performance. Barcelona may not have showcased their full potential in this match, but securing the win and closing the distance to the league leaders could be another motivation and encouragement for the team. From here, they should treat each game is crucial. Barcelona should be looking to build on this result and maintain their momentum in case they Madrid have slip-ups.
