Southampton's 2-0 win over Chelsea in the Premier League on Thursday, December 26, 2019, marked a significant upset in the football world.
Michael Obafemi broke the deadlock with his first goal of the season, bursting inside from the right and curling the ball into the top corner after a tight opening half hour.
Frank Lampard's decision to change Chelsea's formation from 3-4-3 to 4-2-3-1 at the break nearly paid off, but substitute Mason Mount's assist was wasted as Tammy Abraham flashed a shot into the side netting.
Nathan Redmond was denied by Kepa Arrizabalaga on the break but coolly finished for the visitors' second after an impressive team move to silence Stamford Bridge.
The hosts struggled to break down Southampton's tight defence, and Ralph Hasenhuttl's side rose to 14th, three points clear of the relegation zone, building on last weekend's win over Aston Villa.
Chelsea, meanwhile, stay fourth with 32 points from 19 games and must pick themselves up for their visit to Arsenal on Sunday.
