Right now the standings do not really scare me because the points difference between the top four isn't much and at such you can't really tell who is going to clinch the title considering the inconsistent run of all the top four teams. Further more, the standings goes to show how bad Real Madrid and Barcelona have been performing which was what gave room for Athletico Madrid to overtake both of them to the top.
Yet a point difference can win the title for a club, but yes let's not judge with that , there's no too much difference between them but Barcelona is so screwed at the moment as they will be having a game less which means that could already be upto 6 points gap from the first position.
Realmadrid can still work with the single point margin between them and ATH but after Barcelona losed 3 points to Athletico, Realmadrid is more like giving them a 5 points gap unless they losses their outstanding game, this is why I think they are so screwed.
Hence,all they(Barca) can do for now Is wait to utilize chance that comes from both teams flop, that's if they make use of it but apart from that they are getting left behind from the league title race.
