I think Real Madrid in this match was very quickly satisfied, so the satisfaction they felt in such a rushed time meant that in the end they had to be satisfied with a draw.
Real Madrid may be leading the league table, but I doubt they are quite satisfied with the late-game tie.
They had already won this game, but their defense was unable to hold up to the pressure from the Atletico Madrid team, and they drew the match with late late-minute goal.
There are still games for the Laliga League to play before the season is up, and every victory counts. Still, a draw point is preferable to nothing at all. Real Madrid needs more wins to be able to keep up with leading the Laliga table.
The draw was clearly very disappointing for Madrid, but the additional point is also something to be grateful for, especially since the tension in the Madrid derby match is always tight. But I'm still quite confident that Madrid will be able to dominate the standings and if I don't exaggerate then Los Blancos will still be champions this season.
