also modern English, because of the Norman Conquest, borrowed a large percentage of its vocabulary from the Latin language. The Roman or Latin alphabet is the most widely used writing system in the world used by the greatest number of languages. Rome has long hosted artistic communities, foreign resident communities and many foreign religious students or pilgrims and so has always been a multilingual city. Today because of mass tourism, many languages are used in servicing tourism, especially English which is widely known in tourist areas, and the city hosts large numbers of immigrants and so has many multilingual immigrant areas. Sports Association football is the most popular sport in Rome, as in the rest of the country. The city hosted the final games of the 1934 and 1990 FIFA World Cup. The latter took place in the Stadio Olimpico, which is also the shared home stadium for local Serie A clubs S.S. Lazio, founded in 1900, and A.S. Roma, founded in 1927, whose rivalry in the Derby della Capitale has become a staple of Roman sports culture. Footballers who play for these teams and are also born in the city tend to become especially popular, as has been the case with players such as Francesco Totti and Daniele De Rossi (both for A.S. Roma), and Alessandro Nesta (for S.S. Lazio). Rome hosted the 1960 Summer Olympics, with great success, using many ancient sites such as the Villa Borghese and the Thermae of Caracalla as venues. For the Olympic Games many new facilities were built, notably the new large Olympic Stadium (which was then enlarged and renewed to host several matches and the final of the 1990 FIFA World Cup), the Stadio Flaminio, the Villaggio Olimpico (Olympic Village, created to host the athletes and redeveloped after the games as a residential district), ecc. Rome made a bid to host the 2020 Summer Olympics but it was withdrawn before the deadline for applicant files. Further, Rome hosted the 1991 EuroBasket and is home to the internationally recognised basketball team Virtus Roma. Rugby union is gaining wider acceptance. Until 2011 the Stadio Flaminio was the home stadium for the Italy national rugby union team, which has been playing in the Six Nations Championship since 2000. The team now plays home games at the Stadio Olimpico because the Stadio Flaminio needs works of renovation in order to improve both its capacity and safety.
