Mr Di Francesco describes himself as a ‘traditionalist’ and says that he uses a method honed in Naples to make his world-famous pizzas.

Speaking to CNN about his win, he said: “It’s been an amazing reaction. Honestly, I just went to Naples to do what I love. I didn’t think it was going to make such a stir.

“With a lot of other pizzas it’s easy to mask the flavour with toppings, so you don’t really get the flavor out of the dough. With a margherita there is no hiding anything that isn’t right.”
