It's ne of life's great mysteries: how has Diego Costa gone 6 years without being sent off?
The Chelsea striker put in a typically bullish performance against Watford, shoving Juan Carlos Paredes to the ground, squaring up to Chico Flores and generally antagonising referee Mike Dean.
Now this surprise you to read this: but this is not the first time Diego Costa has got away with metaphorical murder on the football pitch.
It's six years since his last sending off, but in that time the Spanish international has committed a number of indiscretions which would ordinarily be deserving of a red card.
We examine the case against the nastiest man in the Premier League.
The time he appeared to hit a Hornet...
The time he ran over Serge Aurier...
The time he nutted David Luiz....
The time he pulled off the no-look headbutt...
The time he threw (yes threw) spit at Sergio Ramos...
The time he scratched Gabriel Paulista's neck...
The time he stamped on Emre Can...
The time he tried to pull Koscielny's eyes out...
The time he kicked out at Skrtel...
And then headbutting him for good measure...
