Instead of taking advantage of Girona's previous draw by winning, Real Madrid instead played a draw against Atletico and even though they only got one point, Real Madrid still topped the standings with a difference of 2 points from Girona. It should have been a 4 point difference if they had won against Atletico but Marcos Llorrente's goal denied them the victory that was in sight. Real Madrid repeatedly had opportunities but their finishing was far from expected.
Apart from that, Ancelotti's selection of players in the second half was also poor and instead of adding attacking type players, Ancelotti seemed to just want to play it safe with that slight advantage. Ancelotti should have included Vinicius instead of Dani Ceballos. The result was that with minimal defenders, Real Madrid conceded in the final minute because Atletico always attacked attacks through aerial passes and took advantage of the height of their players. Real Madrid had to accept this draw because with the limited options in defense they at least did not lose to Atletico.
A very painful result for Real Madrid because they had to draw after Atletico Madrid managed to equalize in extra time. However, I can understand this result, because these two clubs are strong clubs, and in the last two meetings, they also beat each other, so this result is not that surprising to me.
But I agree with you about the transition of substitutions, why doesn't Ancelotti try to add to their goals rather than trying to keep the score. Because winning by 1 goal would be very risky for them, because the opponent could also equalize the score with 1 goal, and sure enough that happened in the final minutes. 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.
Actually, Real played a very dominant game. After the turnovers, they immediately pressed and won the ball back. Atletico tried to take advantage of Real's lack of centre backs by trying to score a header throughout the match and at the end of the match, when there was no centre back to score a header, Atletico scored. I didn't understand why Brahimin, who played brilliantly throughout the match, came off before Rodrygo and Ceballos came on. Real lost 2 points in a very good game because of wrong last passes, selfishness and wrong substitutions. If they beat Girona next week, it's still over.
