The difference is already apparent in Barcelona's higher scoreline than Real Madrid's.
Real Madrid only managed one goal against Osasuna, and even worse, Real Madrid was playing at home against a less formidable team.
I think betting on Barcelona to win the title this season is more promising than betting on Real Madrid.
It is clear that Real Madrid is currently in a bit more difficulty than Barcelona, but Real can always have their say. If they manage to find a solution to the situation, they can easily compete against Barcelona, who are currently the favourites, but they will surely be caught by Madrid.
