Colourblind coach left red-faced

A German football coach is a laughing stock after mistaking the referee for one of his players and urging him to score.

Ralf Rangnick, 48, who coached Bundesliga sides Stuttgart and Schalke before taking over regional team TSG Hoffenheim, stood up and began yelling to one of his players to "move yourself".

But he was embarrassed to discover that the 'player' was actually the referee.

Rangnick said the mistake came from his colour blindness which makes it difficult for him to distinguish between red and green.

"We normally play in blue but were wearing our new red away jerseys and the referee was in dark green. I simply got them mixed up," he said.
