Bournemouth stunned Chelsea with a VAR-cleared winner to claim their first win in six games.
Dan Gosling hooked over home keeper Kepa in the 85th minute from close range- and was ruled onside after a video examination.
The Blues had piled on on a ton of pressure but failed to create any major clear-cut chances, although visiting ‘keeper Aaron Ramsdale had to make an excellent save in the 71st minute to block a close-range header from Emerson.
Both teams were in need of a lift with Chelsea having endured three setbacks in the last four games and Bournemouth on a run of five straight defeats.
It was Frank Lampard’s side who posed more of a threat early on with Mason Mount forcing a fine save from Aaron Ramsdale in the eighth minute after Jorginho’s clever ball over the top set him up.
Tammy Abraham then clipped just wide for the home side after Cesar Azpilicueta crossed from the right in the 17th minute.
Christian Pulisic had a close-range header blocked in the 24th minute as Chelsea cranked up the pressure and the possession without success.
There was a narrow escape for the Cherries’ Jack Stacey when he headed just wide of his own goal after Abraham dropped a tricky ball in the box in the 38th minute.
The visitors finally raised a glimmer of hope when first Dan Gosling and then Ryan Fraser had efforts blocked in the 42nd minute – but Bournemouth could have been happy enough keeping it goalless by half-time.
Eddie Howe’s men delivered the first threat after the break when Josh King broke clear in the 51st minute. But he was expertly halted by Kurt Zouma’s challenge.
Also, Leicester were dealt huge a blow in the Premier League title race as they were held to a draw by a battling Norwich at King Power Stadium.
The Foxes, who remain second, now lie 10 points behind league leaders Liverpool, following their hard-fought win over Watford in Saturday’s early game.
Norwich, who were impressive, deservedly took the lead when Teemu Pukki slotted home after being sent through by Emiliano Buendia.
But their lead only lasted 12 minutes as Leicester equalised when Jamie Vardy’s bullet header was turned into the net by Norwich keeper Tim Krul.
Both sides pressed for a winner in an entertaining second half, with Vardy twice going close, but neither side could find a way through.
The point sees Norwich close the gap on Aston Villa and Southampton, who play in Saturday’s late game, to three points but they remain 19th.
Norwich have already lost to fellow Premier League strugglers Southampton, Watford and West Ham this season, preferring, it seems, to save their best performances for the big games.
Having taken points off Manchester City, Arsenal and Everton, they continued the trend at Leicester and produced a fine performance against the division’s in-form side.
They played with confidence throughout and, while there were a few nervy moments at the back, they threatened the Foxes’ goal consistently.
Even after Pukki had scored with a nerveless finish, he continued to find himself in space behind the Leicester backline and he could well have netted again had it not been for excellent defending from Caglar Soyuncu and Ricardo Pereira, who both produced potentially goal-saving blocks.
Meanwhile, Todd Cantwell shone on his return to the side, playing with a real swagger, while Buendia impressed with his ball-playing ability.
However, despite this confidence-boosting result the Canaries still sit in the relegation zone as we near the midway point in the season, illustrating that they have not been able to produce performances like this one consistently enough.
