Sunderland went second in the Premier League table after stunning Chelsea 2-1 at Stamford Bridge with a 93rd-minute winner from Chemsdine Talbi.
It was the stuff of dreams for Black Cats supporters, who saw Talbi run onto a lay-off from fellow sub Brian Brobbey before coolly rolling the ball into the bottom corner to clinch a shock victory. The Sunderland bench emptied as their players raced towards the travelling fans in delirium.
The rest of Stamford Bridge was stunned. Chelsea had won four in a row going into this and led after just four minutes through Alejandro Garnacho's first goal for the club. But Wilson Isidor tapped in an equaliser after a long-throw caused chaos in the Chelsea box and from then on Sunderland frustrated their hosts.
Garnacho hit the side-netting twice in that first 45 and was denied on the angle by goalkeeper Robin Roefs. But after the break, a deflected shot from sub Estevao was as good as it got for a blunt Chelsea team.
Their youngsters may have put five past 10-man Ajax in the Champions League in midweek but they couldn't pick a way through here. And then there was the sting in the tail, Talbi delivering a moment to treasure for Sunderland and their supporters who are enjoying the thrills of top-flight football once again.
Chelsea badly missing a No 9
Marc Guiu was one of three teenage goal-scorers against 10-man Ajax in the Champions League on Wednesday and had his chance to impress in his first Premier League start for Chelsea - up against the team he'd briefly been on loan at earlier this season.
But on this evidence, Liam Delap's pending return from injury cannot come soon enough. The England man could be involved in midweek Carabao Cup action - and Chelsea are in real need of a central threat on this stage.
Cole Palmer's creativity is another big miss for a Chelsea team that struggled to carve a way through Sunderland's well-organised defence. That was illustrated by the Expected Goals figures, which showed Chelsea at 0.97 to Sunderland's 1.16 - despite the hosts having 69 per cent possession.
But Guiu was bullied by Dan Ballard, unable to find an angle to receive a pass from his team-mates and then unable to retain possession when he did get it. After 76 minutes he was withdrawn having had just 10 touches.
Joao Pedro later went up top, with sub Estevao going to No 10 but still Chelsea struggled to produce meaningful moments. It was an afternoon to wonder why there was such eagerness to offload Nicolas Jackson in the summer.
Enzo Maresca memorably insisted on playing down any hype about his team in the first half of last season. This performance was evidence no one should be getting carried away by their recent run of wins.
