After 4 consecutive league games without a win, Barcelona finally delivered. Maybe Valencia was not the strongest rival (19th place currently) but 7-1 was still very impressing.
Right now Barca has the best attack in the league with 59 goals scored, which averages to over 2.8 goals per game. Unfortunately for them, it's the points that counts, not goals. Points-wise they're still 7 behind Real, as Real didn't have any problems defeating Valladolid (3-0), so I have very little hope for them to stop Real from defending their title.
It's true that points are the main thing that determines a team's position in the table and of course, a seven-point gap is a big gap and it's difficult for Barcelona to overtake Real Madrid. Unless, for example, Real Madrid is not a top team that has great dominance, then maybe such a gap can still make Barcelona overtake it. But yes, the reality is that Real Madrid is a team with good dominance and also has a great winning mentality, thus it is difficult for Barcelona to overtake Real Madrid.
Because anyway, the only way Barcelona can overtake Real Madrid is by hoping for Real Madrid's inconsistency by having several consecutive defeats. But unfortunately, when Real Madrid are already at the top of the table for the second half of the season, overtaking Real Madrid will certainly be a difficult target.
What is certain is that everything is still just assumptions and speculations, we will know more for sure after these teams play match after match until there is a gap that makes it impossible for Barcelona or even Atletico Madrid to catch up. Barcelona is 7 points behind, while Atletico is 4 points. given that there are still many matches until the end of the competition, then there are always opportunities and they are still open for Barcelona, especially Atletico Madrid. at least there are still 17 matches that must be played by all teams competing in La Liga, including the three teams that I mentioned in this post. in every match, whether it's Real Madrid, Barcelona or Atletico, there is always the potential to slip, they could get a draw or some obstacles and problems that they will face later. well, the most consistent team is definitely the champion in this Spanish League. however, Real Madrid is currently leading the standings, automatically they are required to always play their matches to the maximum and will try to advance smoothly without defeat. thus, this season's trophy still belongs to Real Madrid. but once again, the final result still has great potential to change direction.
