Atletico Madrid snatched three points at Real Madrid in yesterday's derby.
Last season's surprise champions weathered a first-half storm after Cristiano Ronaldo's penalty cancelled out Tiago's opener, and their resolve was worth it as they won it in the 76th minute.
Substitute Arda Turan got their winner, but all their players were heroes as budgets were again made a mockery of as Diego Simeone's men won across the city for the second time in two seasons.
Real coach Carlo Ancelotti said: "In the first half we played very well, with aggression and intensity. Then our pace dropped off and to beat Atlético you have to play with intensity at all times.
"I'm worried because it hasn't been a good start to the season, like last year. Fortunately it's just the beginning. I'm certain that we will fix it together, with the necessary calm and self-criticism."
