Having the same number of points over Real Madrid and only 1 point difference over Atletico Madrid requires Barcelona to remain consistent in the remaining thirteen games this season.
This is a tough job for Barcelona. The first thing we are most worried about is player injuries considering that Barcelona are still in several competitions such as the COPA DEL REY and the Champion League.
Against Las Palmas on the 23rd yesterday, for me the victory they got was not easy. Only in the 62nd minute Barcelona were able to score a goal and their second goal was only created in the minute of added time.
Things will indeed feel more difficult towards the end of the season. Because competitive tension will also be higher. Each team will try not to make the slightest mistake. So Barcelona also cannot make the slightest mistake because Real Madrid and Atletico Madrid will be ready to replace Barcelona in 1st place if Barcelona makes just one mistake and loses points. This fierce competition is likely to continue until the last match of this season. This is a bit similar to the competition in the Premier League last season. Where the difference in points is so narrow that the season ends. In fact, last season Man City could become champions there with just 2 point difference from Arsenal. And something similar looks like it will happen in Laliga this season.
