I can't answer that either, that's because the two teams competing for this title are always possible to drop points as long as their opponents play well.
I think we may have to enjoy some tough competition between the two this season, and Real Madrid may have realized Barcelona's potential as well. There is no need to underestimate either one as it is always possible to see the top of the table rotated due to team performance. Regarding team performance, I think Barcelona will still lead because they are already very different compared to last season.
There will continue to be more pressure on Barcelona. The e points difference between Barcelona and Real Madrid is like no point difference because only one match that Barcelona fails to win will close the gap.
Assuming that the point is upto 5 and above I would have believed that Barcelona can win the title. But for now it is still under serious contention and Barce may give up even before El clasico
