Saturday's 1-1 draw at the top in the Madrid derby between Real and Atletico was a great outcome in terms of making things more interesting.
Barcelona didn't waste their chance and caught up with the top 2 by reducing the gap by two points.
I think it's pretty possible we might see a new leader after next weekend.
Real is playing an away game against 9th Osasuna, which might not sound like a threat, but, given Real's players might have less time to recover after today's game with Man City and the fact that both, Real and Osasuna tend to perform much better at home - we could see a split of points between them. If that happens, either Atletico or Barcelona would take that opportunity and jump to the 1st place.
