Barcelona still hasn't shown a convincing performance, the victory this time was quite helped because of the penalty prize, and fortunately, Lewandowski managed to execute the penalty well, the previous match they also almost lost to Villareal because they were behind by the home team, and it looks like they are having quite a problem in the away game because from 3 away matches they have had difficulties if Xavi Hernandez hard to finds their weak points and fixes them immediately then Real Madrid will be very comfortable staying at the top.
I think they haven't got hot for the new season. If this continues then Barcelona will lose a lot of points. They will find it difficult to chase points if the difference in points will be even more.
I think with a good enough transfer from Real Madrid they will be favourites to win again. Although it is only the initial season, Xavi must immediately improve it. Xavi must maximise the potential of players to get maximum results.
If Barcelona drops several points behind the best teams in La Liga at the beginning of the season, it will be very difficult for Barcelona to recover those points and if the teams at the top of the points table perform regularly, it will not be possible for Barcelona to recover those points. Plans should be made so that they do not lose points. Barcelona are currently two points behind Real Madrid, if Real Madrid sign any new players then Real Madrid will become a more consistent team which will make it very challenging for Barcelona to occupy the top position of the points table. Barcelona must improve in the next matches and Xavi must come up with new plans. In order to maintain the top position of the points table for the whole season, we have to play our best from now on.
