Real Madrid and Barcelona have led the La Liga standings for much of this season, with both teams currently sitting at 22 points apiece. However, Real Madrid has a slight advantage in terms of goal difference, which is one of the key factors that determines team position in the league.

Both clubs have had strong performances throughout the season, with Real Madrid having won their last four matches while Barcelona have also been in fine form, picking up wins in all but two of their games so far.

However, it's clear that Real Madrid has the upper hand when it comes to scoring goals, as they have scored more than any other team in the league. In fact, Real Madrid has scored an average of 1.94 goals per match compared to Barcelona's 1.67 goals per game.

This goal difference advantage has given Real Madrid a significant edge over Barcelona in the standings, with them currently leading by just three points after six rounds of fixtures. However, it's worth noting that these standings could change quickly, as there are still many matches left to be played and anything can happen on the pitch.

Overall, it seems that Real Madrid and Barcelona are neck-and-neck in terms of their performance this season, but Real Madrid does seem to have the edge in terms of goal difference. As always, we'll have to wait and see how things play out over the remaining fixtures before making any definitive judgments about who will ultimately come out on top.
