Tottenham Hotspur midfielder Lewis Holtby has posted a picture on his official Facebook page of him and teammate Sandro facing-off ahead of this evening's World Cup semi-final between Brazil and Germany.
Along with the picture of the two Spurs players is the message, "Sandro 'the Beast' Raniere and his Brazilians vs Lewis 'Fritz' Holtby's Germans.
"There will be no friendship today bro."
The two sides go head-to-head at 9:00pm GMT in one of the tightest World Cups in living memory.
And while some Spurs players are now back in pre-season training under new manager Mauricio Pochettino, there are clearly some friendly rivalries as football's biggest tournament reaches its climax.
One thing is for sure, only one of Sandro or Holtby will be smiling when they turn up for training tomorrow morning...
