Yeh that penalty was totally un fair, the referee committed a huge mistakes by awarding such unfair penalty to to barcelona. They didn't even check the VAR despite it not being a clear penalty from a naked eye. la liga must need to take a action against this refree whereas he knew it this is not a valid penalty, but still he handed the penalty to barcelona. Valacano team were too good, they produced multiple chances but barcelona goalkeeper stop every single chance. Any that's how, beyond any doubt we can call it a misfortune of Ray Valacano because they truly deserve the victory but unfortunately unfair decision made it equalizer. At the moment real madrid is in the top ranking, it's true that it's early of the season but if they continue to perform solid just like that and try to utilize their consistency, they can definitely win the la liga title.
Nobody performed well against Rayo Vallecano except the Barcelona goalkeeper. I think Barcelona did not perform well enough to draw this match, they were able to draw the match because of the referee's bad decision. Such a bad performance against small teams at the beginning of the season highlights Barcelona's weakness and makes them suspicious against Real Madrid. They should take every game seriously and fight to win. But every coach and club has a different strategy, I still don't know what their strategy is and why they are showing such a weak performance at the beginning. Maybe they are trying to implement the marathon strategy.
I don't know if anyone noticed but Barcelona attackers are getting a little bit selfish. Early in the game on Sunday Raphinha had the chance to give a good pass to Ferran Torres who was in a better position to score than he was but he choose to hit it.
It may be early days but if they want to retain being champions of Spain then they need to be good in both their attack and defence.
