I blame Ancelotti somehow for all the whole injury crisis that has lead to the defense this weak. I know they could have won aside all that but I expected him to sign some players around the January transfer window but unfortunately he didn't and after that more players got injured and they bottled the league from being top of the table to now hoping Barcelona lose more points. This game was just does kind of game where football happens from the fact that even Vinicius Junior missed a penalty, although still got a goal but they were still wasteful and unfortunate.
He believed he had all the required resources already, but everything happening this season was just as a result of last years effort channeled inot getting the trophies, they played so many games/too much games and that was reflecting in the players somehow this season, signing new players could have helped resting some of this players but it's done already and there are no room for excuse, just as Mancity had no room for excuse, to me their situation is alike just that Realmadrid did performed better than them and still hanging tight to UCL and Copa even though this season could end with them having no trophies 
Currently, Barcelona is hosting Betis at the end of 35 minutes game score is level on 1–1 which is giving Barcelona 4 points lead from Real Madrid after end of 30 rounds this is huge lead for them which giving them good confidence for winning title and also going through for more silverware in this season.
Real Madrid vs Valencia was really shocking result as Valencia which was fighting hard in relegation zone doing impressive job and jump out of danger zone with now have good confidence to beat top sides which surely improving their depth any chance for securing spot into top half of league table.
