Serie A (Italian pronunciation: [ˈsɛːrje ˈa]), also called Serie A TIM due to sponsorship by TIM, is a professional league competition for football clubs located at the top of the Italian football league system and the winner is awarded the Scudetto and the Coppa Campioni d'Italia. It has been operating as a round-robin tournament for over ninety years since the 1929–30 season. It had been organized by the Direttorio Divisioni Superiori until 1943 and the Lega Calcio until 2010, when the Lega Serie A was created for the 2010–11 season. Serie A is regarded as one of the best football leagues in the world and it is often depicted as the most tactical national league. Serie A was the world's second-strongest national league in 2014 according to IFFHS. Serie A is ranked third among European leagues according to UEFA's league coefficient, behind La Liga and the Premier League, and ahead of the Bundesliga, which is based on the performance of Italian clubs in the Champions League and the Europa League during the last five years. Serie A led the UEFA ranking from 1986 to 1988 and from 1990 to 1999.
