La Liga is get even more difficult, despite real Madrid being at the top now, it could have easily been athletico Madrid or Barcelona but some inconsistency from all the top three team has left us in this situation, but I am currently believing that amongst the three clubs Barcelona has more chance of becoming the league champions and I would believe they can easily go for a treble this time around.
Barcelona defeat in the previous few games left them 7 points behind Real Madrid, so what you said honestly I doubt they can win the title. I see Real Madrid now have developed better than at the beginning of the season so I don't think it will be easy to shift their current position. I think the most potential is Atletico Madrid, so I think for now they are the only two competing. But let's look forward, if Barcelona are serious, there is a possibility to catch up on points and compete closely towards the end of the season.
I would want to believe that you aren't new to football, at this time of the season the title is still very open to anyone, and mind you Barcelona and real Madrid still have one more game to go against each other and there would be some difficult games that either team can drop points, so me saying Barcelona can win the league is very possible, but Barcelona would have to be on top form to see this happening.
