With how Real got the win today, we can see that the gap is only four points and Real is missing one game, everyone knows this much ,this is the mathematics of it. But also I would like to point out that Real Madrid is missing a lot more players and that means, if Real was fully healthy all season long, this season wouldn't even be a question, we would have seen Real win it by a large margin. The sad part for Barcelona is that they started great but they ended up not that great at all eventually, including this week. I can see how Real could take the lead eventually, the gap is theoretically one point right now, and that could be beaten in a single week, so its clear that real is doing great and we could see them get it, or Barcelona has to fix whatever is wrong, and do better.
Yes, this great victory of Real Madrid has given them more confidence to occupy the top position. Currently, Real Madrid is in second position with a gap of only 4 points, however, Real Madrid will not lose their points in the next match. Although the second half of the season has not come yet, so there is still a lot to be seen, in the next phase, each team will definitely try to improve their game more. However, looking at Real Madrid's current performance, I think they will definitely succeed in occupying Barcelona's position because Real Madrid is very excited at the moment. Moreover, although Barcelona started very well, the performance I can see at the moment does not seem to be that Barcelona will be able to maintain their top position. However, Real Madrid will try hard to change their position, and since Barcelona will face a normal team in the next match, there will be a possibility of winning that match. Overall, if Real Madrid's players remain healthy and continue to play brilliantly, it is possible to reach the top position. And if Barcelona's play continues to deteriorate, they will have to move away from the top spot.
