From 20 March 2004 to 26 October 2008, Chelsea went a record 86 consecutive league matches at home without defeat, beating the previous record of 63 matches unbeaten set by Liverpool between 1978 and 1980. Chelsea hold the English record for the fewest goals conceded during a league season (15), the highest number of clean sheets overall in a Premier League season (25) (both set during the 2004–05 season), and the most consecutive clean sheets from the start of a league season (6, set during the 2005–06 season). Chelsea's streak of eleven consecutive away league wins, set between 5 April 2008 and 6 December 2008, is a record for the English top flight. Chelsea are the only Premier League side to win their opening nine league games of the season, doing so in 2005–06. From 2009 to 2013, Chelsea were unbeaten in a record 29 consecutive FA Cup matches (excluding penalty shoot-outs).
