Paris Saint-Germain's official Twitter account has labeled Chelsea striker Diego Costa a "fraud" in the build up to Wednesday's last-16 Champions League clash.

The two sides have come face-to-face in each of the last three seasons in the Champions League and there appears to be bad blood ahead of the crucial second leg fixture.

On Tuesday afternoon a Vine appeared on PSG's official Twitter feed showing all sorts of superheroes and villains, with striker Costa in amongst them, and the accompanying strapline asking people to "Spot the fraud."

This came after PSG manager Laurent Blanc said his side must "keep cool in the face of provocation" from Costa.

The Spanish striker is no stranger to antagonism and we wouldn't be surprised if this tweet ended up backfiring on the Ligue 1 side.
