Tottenham enjoyed an unforgettable start to 2015 as Chelsea were disposed of in remarkable fashion, with Jose Mourinho's side shipping five goals as the Premier League title race burst wide open.
Spurs have rarely had the bragging rights in this fixture - just three times in 45 Premier League encounters, in fact - but this was a night those inside White Hart Lane will not forget in a hurry.
Harry Kane's brace was complemented by efforts from Danny Rose, Andros Townsend and Nacer Chadli as league leaders Chelsea were embarrassed 5-3 in an enthralling New Year's Day battle.
This was the first time the Blues had conceded even four goals in one match under Jose Mourinho and a defeat so heavy that Manchester City joined them on goal difference at the top of the table.
It was a result few could have predicted, especially when Diego Costa tapped home from close range after 18 minutes.
Spurs rallied wonderfully, though, and went in at half-time boasting a 3-1 lead as Kane levelled with a fine effort from 25 yards, before Rose netted and Townsend struck from the spot.
Kane won that penalty and added a classy second goal shortly after half-time - his sixth in as many matches - with Chadli adding a fifth after Eden Hazard had pulled one back for the visitors.
John Terry's late goal led to a nervy ending but Spurs would not be prevented from a famous end to a winless run of 10 matches in league and cup against Chelsea, which stretched back to April 2010.
