New Chelsea manager Thomas Tuchel has a familiar face in the dressing room in the form of Christian Pulisic after the pair worked together at Borussia Dortmund a few years ago.
And it seems the American is only too keen to help the new boss out - especially when it comes to avoiding embarrassing nickname mix-ups.
Just before the start of the second-half in Wednesday night's goalless draw with Wolves, Tuchel stood on the touchline and called captain Cesar Azpilicueta over to issue some instructions.
