If this was Barca from 3 seasons ago, I would say that the league is already over considering they are ahead by 7 points. However, Barca are massively reliant on Messi right now, Suarez is a shadow of himself and Dembele is out for four months. I'm not convinced that Barca won't drop 7 points before they play Real.
Having said that, this is a pooor poor start by Madrid, still hungover from the double which is understandable.
