1937 Monaco.

Manfred Von Brauchitsch - Rudolf Caracciola.

Neubauer was furiously giving signals to Von Brauchitsch to let Caracciola pass and the driver replied by sticking out his tongue to the team manager as he passed the pits. Brauchitsch finally let Caracciola through as he knew the latter had destroyed his tyres and had to make a pitstop. Then Von Brauchitsch went on to a fine but controversial victory.
