Extracting the urine

In Robert Peston's Among The Managers, a Radio 4 programme , comparing football and business managers, Sam Allardyce revealed: "I like to start off in the morning with a urine test, testing the nutritional value of breakfast, that kind of thing," said Big Sam, referring to his players. We've had many a manager in the past who's taken the urine, but never before in the name of science.
