yes, real madrid and barcelona have always challenged each other in a spectacular way to win the league since the past, after all they are the two strongest teams in the league, not by chance
In my opinion, much of their strength comes from a very large fan base that allows them to raise a lot of money and therefore be able to invest
The rivalry between the two teams in the hunt for the title always provides excitement for their fans, this season they are also at the forefront of the competition at the top of the standings. Barcelona relies more on academy players to improve the team's strength, while Real Madrid prefers to bring in top players because they have healthy finances. The role of fans greatly influences the atmosphere on the field, but the central point lies in the performance of the players. It must be admitted that Barcelona is currently better than Real Madrid in maintaining its performance.
Your claims are undisputed and I must say that for Real Madrid to finish as the league title winners, they will need to improve their performance in the field as they have been this season. All meetings between this two clubs this season have ended in favour of Barcelona while they still have one match head to head between them to be played. The matches in the La Liga they will be facing each other is not okay to give the winner to one team amongst them, it involves the collective effort of them playing against all teams in the league before they will get the chance for the league title. Each team can play whomsoever they like now, but their head to head match is most important and the winner in that match has the more chances of winning the title than the other team.
