The war against fake merchandise will be stepped up as Manchester United brings its top stars to the Vodacom Challenge in South Africa.
Teams of experts will patrol grounds at training sessions and matches to ensure fans are able to buy merchandise without fear of it being counterfeit.
In the last five years, United officials, working with organisations in South Africa, including customs, have seized over 90,000 items valued at more than £1.2 million including shirts, hats, scarves and badges.
“We would urge fans to buy only official merchandise from authorised outlets," said United Chief Executive David Gill. "Fakes are generally of inferior quality and you can rarely return an item when anything goes wrong, as the seller has moved on. Official merchandise is better quality, which is what our fans demand and deserve.
“We are grateful for the co-operation of the enforcement authorities in South Africa and are confident we can protect many of our loyal fans who want to show their support for the team at the Vodacom Challenge.”
