Predicting that Real Madrid is going win La Liga is like predicting that Bayern Munich is going to win the 1. Bundesliga. But for some good reason there are two clubs that could thwart those standard plans and bring about a surprise for all the football followers around the world. It is called a surprise because it wouldn't be normal. Hence, it's quite standard to think that Real Madrid is most likely going to win the title, but give it some time for now. I concur with you and I do because it is less likely that Girona can go at this pace until the end of the season, but Real Madrid is not an almighty team either. Some bad circumstances can cause them to lose games. Bur first of all Girona has to beat Real Sociedad.
In the last 10 years, Real Madrid have only won the La Liga title 3 times, while Bayern have won 10 out of 10 titles, so I think this anology is inappropriate. If we take the current season, then surprisingly the picture is the opposite: Real Madrid has a higher chance of winning La Liga than Bayern has to win the Bundesliga.
Girona obviously cannot keep up with Real's pace and has begun to lose points frequently, Real's advantage over the other two historical rivals is 10 points, so I think that the question of the title holder is 95% closed.
