The Argentine has guided his team to six unbeaten Liga matches against their bitter rivals, the best run in the history of the club from the Spanish capital
Simeone's side triumphed in the derby clash with Real Madrid, Antoine Griezmann netting the only goal of the game early in the second half.
Victory pulls Atletico within five points of La Liga leaders Barcelona, who face Sevilla on Sunday, while Real remain nine points adrift and with a mountain to climb if they are to make a genuine title challenge with 12 games remaining.
The win continued Atleti's recent strong record against their city rivals, having also prevailed in this fixture in each of the past two seasons.
"We take it naturally, to be able to win here," Simeone told a news conference. "Football is marvellous - it has these things, from outside it's hard to explain.
