Schalke's official Twitter account has made a cheeky post of their squad in training before they take on Chelsea in the Championship League.
Showing clear disregard for the Chelsea signage at the training ground, they took a picture right next a sign asking for no photography to be made.
It was a snap which raises a smile, but the Blues will be hoping to have the last laugh when they kick off their Champions League campaign against the German side tonight.
Chelsea have won every game they have played so far this season, and impressed all watchers with the manner of their performances.
They will now be looking to transfer their league form into European action and they will need to show their killer touch if they are to avoid an upset.
Schalke may not be one of the major contenders to win the competition, but they are a decent outfit and they will pose a threat to Jose Mourinho's side if they are not at the top of their game.
