There are few football clubs in the world that attract as much interest in the modern game as Chelsea. Whether it is the latest observations from former coach Maurizio Sarri, his successor Frank Lampard, big-money transfer targets, the style of play or results in Europe, everybody thinks they know what's happening - or at least has an opinion on it.

The arrival in 2003 of Russian billionaire tycoon Roman Abramovich as owner turned a glamorous club with a long history of under-achievement, into an international powerhouse. After one championship in 99 years, the Blues have, in a dozen years, won five Premier League titles, plus the UEFA Champions League, two UEFA Europa League titles, five FA Cups and three Football League Cups. The club always was a magnet for well-known names - vaudeville legend George Robey played for the Pensioners in the club's earliest days - and, in the modern era, Stamford Bridge has become home to a dazzling array of world stars. From Ron 'Chopper' Harris and Ken Bates through Ruud Gullit, Roberto Di Matteo and Glenn Hoddle to Jose Mourinho, John Terry, Zola, Diego Costa and Eden Hazard, there is no lack of characters to draw on for quotes.
