~snip~ it will be too early to say Real Madrid have lost the La Liga. We all know that we are not 100% sure that Barcelona will continue to be winning all the games as they are right now, and Real Madrid will continue trying to win their matches again. So I think they both still have a lot of hard work to put in.
That's the simple math. But the league has many matches that will be grueling. That will be a difficult factor to predict, so a 9-point gap is not impossible for Real Madrid to catch. This is because there are still many matches yet to be played. I believe there will be many surprises that happen. I read many rumors that Real Madrid will take advantage of the transfer market to buy players. So Real Madrid might be getting better.
