Honestly Real is unbeaten again, they are 4 of 4 and they are winning all games so far, but they are not clear of anything yet, it is just 4 games so it is understandable but they are only 2 points head of Barceloan which changed the whole team and built something amazing.
So, I am guessing that Barcelona is actually in a better spot than Real, and you may wonder how first would be worse than second, but the reality is that if you give teams something to chase for, that makes them better, so being in second means you are running after the first, but being first means you are running away from second and that is always much harder in psychology for sure.
in four matches madrid has always been consistent in their performance, in four matches they won all matches. and I think it's a pretty good achievement at the start of this season, although Benzema's performance was not very good in that game despite not being able to score a goal. but overall real madrid's game is quite solid, and of course in that match, they will not easily beat manuel pellegrini's squad who in fact in their three matches have always played well. and in the match against Madrid, it was the first defeat for the men of Manuel Pellegrini's squad.
On the other hand, Barcelona has found the rhythm of the game, the chemistry between the players begins to build. lewandowski has done very well in his last three games.
So I think the rivalry between these two big clubs has just begun.
