Yes, the gap between Barcelona and Real Madrid is now very short. You might consider one difference between these two teams, I see that Barcelona has won one more match than Real Madrid. As you mentioned that Real Madrid will not be defeated against Real Betis, it is completely correct because they will never want to be defeated against this team, they are actually hoping to be at the top. Now it seems to me that if they win today's match, they will be at the top. Just as there is a match for Madrid today, there is a match for Barcelona yesterday. Now maybe these two teams will try to play very carefully.
I did not really follow La Liga like before when Barcelona really disappointed as Real Madrid closed the huge point difference and overtook Barcelona but the result I saw just now surprised me. Both club have the same points but Barcelona is leading with goals. They have both played 25 matches. If Real Madrid won today, that does not mean the club will stay at the top. One club must fuck up bit I think Barcelona is back to their peak performance.
