The fact that there are 12 points difference between Barcelona and Real Madrid tells us the story of the season thus far. Real Madrid has been doing well in the UCL just like they always do, but when they are bad in the league that proves that they are not as good as they used to be, like last year they were better and I do not mean like they were better than Barcelona, that is easy because Barcelona was bad, it is not about standings, it's about how many points they collected by this time, and it was probably higher.
So, overall they are worse this year and just because of this fact I feel like they may not end up winning the UCL title this year, not again at least.
Last year Real Madrid was not a favored team to win UCL but somehow they were able to beat Chelsea and even Man City as the strongest candidate to win the cup. It's unfair to judge that Real Madrid couldn't win UCL just because of their poor performance in LaLiga. In otherwise, Barcelona playing well in LaLiga yet they couldnt did anything in Europe competitions.
