Barcelona should be able to take advantage of this momentum well, to collect more points before Real Madrid rises and performs consistently again. We realize that Hansi Flick squad is not as ideal as Real Madrid, with a squad that lacks quality rotation options, Barcelona can stumble at any time. However, Barcelona efforts will be tested by Girona in the next match, last season Barcelona had to admit the prowess of Michel squad in two meetings.
I also agree with you that Barcelona should take advantage of this opportunity. The Barcelona boys are in excellent form. The players are now very confident after a big 7-0 win in the last match. This squad is capable of performing well. So now they have to continue their winning streak. On the other hand, Madrid's performance is somewhat erratic. So the Barcelona team is already 4 points ahead of Madrid. If Barcelona can increase this gap, then Barcelona has the possibility of winning the La Liga title.
Madrid's squad is very strong but Barcelona's squad is not strong enough yet. Lots of talented players in the squad. But the performance of most of the players is erratic. However, young players like Yamal and Olmo continue to perform well, which is why Barcelona's overall performance is stable. However, it is not certain whether these players will be able to maintain consistency.
The only way Barcelona can win the league title this season is when they play against Real Madrid in El Clasico and defeat Real Madrid, We should remember last season when Barcelona was at the top of the league table and after the El Clasico Real Madrid took the lead in the table, Real Madrid started playing last season with ending matches draw but after they play against Barcelona they win the match and top the league, Barcelona winning 7-0 is not something that will make us think that they can win the league title this season, Real Madrid never lose any match they play and I can't judge them or predict who is going to win the league.
We all know that Barcelona players are very talented and they can play against Real Madrid but defeating Real Madrid is not going to be easy for them, Real Madrid players are very strong and whenever Real Madrid plays against Barcelona, Barcelona players usually get injured, Even if Barcelona have Dani Olmo Real Madrid will still beat Barcelona because even when Dani Olmo is in Leipzig Real Madrid used to beat Leipzig so I don't think we should think that Barcelona can win the league.
