#4 Charlton Athletic vs Chelsea – 2003
Roman Abramovich had just spent his first Christmas as Chelsea owner, but was in for a rude shock the very next day. On Boxing Day, Chelsea travelled to The Valley to play fellow Londoners, Charlton Athletic. The expensively assembled Blues squad was dismantled as Charlton spread some festive cheer among their fans.
Herman Hreidarsson opened the scoring within the opening minute as Chelsea had barely even got started. John Terry pulled the Blues back into it with his equaliser.
But from there on, it went all downhill for Chelsea. Goals from Matt Holland, Jonatan Johansson and Jason Euell gave the Addicks a comfortable 4-1 lead. The Icelandic forward Eidur Gudjohnsen scored a late consolation for Chelsea, and it was too little, too late.
