Again and again Barcelona failed to get three points against teams in the bottom zone, or maybe Xavi is making some tactical and strategic experiments that are still not optimal in these two easy matches. I don't understand what happened, because even though Barcelona are relatively safe at the top of the La Liga standings, but Barcelona shouldn't have failed to win because in this match Barcelona only played against mediocre teams.
Lewandowsi also doesn't seem to have a big effort to score many goals in every Barcelona match, so it is difficult for Barcelona to take advantage of the opportunities they get to score a goal. Indeed, it doesn't matter because Barcelona still won 1 point, but if results like this continue then of course Barcelona are experiencing problems in their performance.
