(DailyMail) - Question: What do Mister Potato crisps and Smirnoff vodka have in common? Answer: They are both official sponsors of Manchester United Football Club. And they pay handsomely for the privilege. These two distant products may appear to have little to do with football but they can wear the same badge as Robin van Persie, Wayne Rooney and Co because of United’s exhaustive quest for maximum commercial revenue. That figure is now approaching an astonishing £130million a year and will only continue to rise. No wonder United recently became the first sports team in the world to be valued at $3BILLION.
