Zinedine Zidane was unable to mark his 50th La Liga game in charge of Real Madrid with a 40th victory as Antoine Griezmann's strike grabbed a 1-1 tie and continued the Blancos' poor recent record against their city rivals.
Zidane's countryman is a familiar tormentor – his first loss at the helm came when Griezmann scored the only goal for Atleti at the Santiago Bernabeu last season.
That was the only time Madrid have failed to score in La Liga during Zidane's tenure and their on-going scoring streak is a club record standing at 42 games thanks to Pepe's second-half header on Saturday.
The Frenchman has only been beaten twice since that initial derby disappointment - by Sevilla and Valencia this January and February – and his 78 per cent win ratio stacks up well alongside his recent predecessors.

Jose Mourinho and Carlo Ancelotti managed 76.3% and 75% from 114 and 76 La Liga games respectively.
Zidane succeeded Rafael Benitez last January, largely as a result of the current Newcastle United manager falling short of these standards with 11 wins, four draws and three defeats – a 61% ratio.
