The Spain international's face appeared in a Vine of superheroes as the French champions chose to make fun of the former Atletico Madrid striker's protective face mask
It's not advised to get Diego Costa too fired up if you are about to take on the Chelsea striker, but that is exactly what Paris Saint-Germain may have done.
The Ligue 1 champions have been running a prominent social media campaign ahead of Wednesday's Champions League clash at Stamford Bridge as they bid to knock the Blues out for a second season running.
But one post caught more attention than most after PSG asked fans to 'Spot the Fraud' among a series of superhero pictures put together in a Vine post.

On the surface this may have confused some supporters, but some eagle-eyed viewers will have spotted Costa's face in among the images with the French outfit seemingly making fun of the Spain striker's protective mask.
