Ruben Loftus-Cheek headed home in stoppage time as Chelsea escaped South Wales with a controversial 2-1 win over Cardiff, writes Sky Sports.
Loftus-Cheek, on as a second-half substitute, steered his header into the corner of the net from Willian's cross (90+1) to seal Chelsea's comeback after Cesar Azpilicueta's header from an offside position had cancelled out Victor Camarasa's fine opener.
Cardiff, who also saw two good penalty shouts turned down, had looked set for a precious three points in their fight against relegation when Camarasa clipped a fine first-time effort past Kepa Arrizabalaga on 46 minutes, prompting boos and jeers from the visiting fans towards Maurizio Sarri.
But Azpilicueta, two yards offside when Marcos Alonso flicked the ball into his path, levelled on 84 minutes and after Antonio Rudiger was fortunate to escape a red card for hauling down Kenneth Zohore, it was left to Loftus-Cheek to leave Cardiff boss Neil Warnock fuming on the touchline.

The result lifts Chelsea to within a point of the top four, with Cardiff five points adrift of safety, albeit with a game in hand on Burnley.
A tepid first half saw Chelsea dominate possession but fail to muster a shot on target, with Josh Murphy creating the best chance of the opening 45 when he bent a shot just wide from the angle after working some space in the box.
Meanwhile, Sean Morrison should have won a penalty for the hosts when his shirt was tugged by Alonso, with Pedro's fizzed effort over the bar on 10 minutes the closest Chelsea came to threatening Neil Etheridge's goal.
But the game sparked to life straight after the break when Chelsea failed to properly clear a set-piece and Harry Arter's low ball into the box was met by Camarasa, leaving Kepa with no chance.
Sarri's response was immediate as he threw on Eden Hazard, who started the game on the bench, and the Belgian drew a yellow card from Arter before Morrison should have had a second spot-kick - Rudiger this time hauling him to the ground.
At the other end, Morrison was putting in a heroic shift, blocking Pedro's shot before intercepting Hazard's dangerous ball across the six-yard box.
Willian then flashed an effort across the face of goal, but with Cardiff looking solid in defence, they were undone by Azpilicueta's offside header.
Zohore was then set free only to be hauled down by Rudiger, but with the home fans and players baying for a red card, referee Craig Pawson produced a yellow, sending Warnock apoplectic.
And his mood would only worsen, as Loftus-Cheek's late intervention left him staring down the officials as they left the pitch to a chorus of boos.
