Diego Maradona steps into the world of high culture on Monday when epic tales of World Cup glory as well as reflections on his colourful private life are played out at Naples' famed Teatro di San Carlo. Sadly for the Argentine, who was idolised when he starred for Napoli 30 years ago, his presence at the world's oldest active opera house has sparked an angry reaction amongst the country's artistic community. "The San Carlo has a rich history, it has welcomed the greatest singers and orchestras. There is music, opera and ballet -- it is not the place for football. It is totally inappropriate," sniffed leading composer Roberto De Simone. Maradona, characteristically, has shrugged off the controversy, as have his fans. "It's very emotional to see how much love there is for me," said 56-year-old Maradona on Sunday as he met the press.    –Afp
