Currently, Barcelona have better and consistent performance in this season than Real Madrid although not unbeaten yet but loss many points after being draw in three matches. Real Madrid remaining three points left from Barcelona on current standings position awhile and the el clasico match very crucial for both teams to secure their top standings position and Barcelona won't loss their opportunity with first standing place.
Yeah Barcelona have a great performances this season compared to their last season performance, but this the right time for them to put in much efforts if not the Real Madrid mighty take over the top standing from them. Because the way Madrid performance is moving on currently now if care is not taking they might chances Barcelona after there upcoming match.
Barcelona are about to lose there consistency with the kind patterns of the game their playing this day, compared to how they started the league this season, and if they didn’t maintain their performances and continue to lose every of their matches or draw they lose their first standing in the table.
Now it depends on how Flick contributes in the end because after all, when it comes to consistency it's clear that Flick is ultimately in charge and Barcelona's performance depends entirely on how he schemes the attack or rotates players so that it doesn't disrupt their performance in a busy schedule.
The previous Xavi era mid-season was always Barcelona's main problem in maintaining consistency and this is likely to happen again in the Flick era when he is not really able to maximize the players available in a fairly busy schedule.
But on the other hand, the expectations for Flick still remain great now especially with a very good early season performance even though there are some matches that are not too expected in terms of final results but so far they are still very solid in collecting points and this is certainly a very good expectation for Barcelona this season.
