Real Madrid players woke up after and scored 3 nice goals and they are 2 points behind of Barcelona with a game less than them, so theoretically Real Madrid could pass to the first place.
I did not watch this match but based on the statistics of the match it seemed that both teams played with attacks each other with 10 shots and Real Madrid dominated with 7 on target and Girona 4 on target yeah actually not too bad and the final result Real Madrid can secure 3 points. As you said Real Madrid is only 2 points behind and next week they will take over the top of the standings because Madrid has one match to play against Rayo Vallecano.
On the other hand Barcelona is really disappointing when they only played draw against Betis, in the last 5 matches Barcelona only won once and lost 2 times, we don't understand what the problem somehow their performance worsened even though at the beginning of this season Barcelona always played aggressive.
