CHELSEA maintained their unbeaten run under new boss Thomas Tuchel with a gritty 2-1 win at Sheffield United.
Mason Mount scored to see the Blues ahead at half-time.
But Antonio Rudger passed the ball into his own goal nine minutes into the second period to give the hosts some hope.
However their relegation fears increased when Jorginho netted from the pentalty spot after keeper Aaron Ramsdale fouled Timo Werner.
Here, Simon Phillips rates how the Chelsea players fared on their trip to South Yorkshire.
Edouard Mendy – 6
As always there wasn’t much for Mendy to do in the first half.
He couldn’t do anything about Rudiger’s mad moment, and made a good save at the death.
Cesar Azpilicueta – 6
Not his best game in a Chelsea shirt and he really struggled to deal with United’s high press, as did many of the Chelsea players.
But the captain did his job defensively and helped the team.
Andreas Christensen – 7
Made some very good bursts forward with the ball and looked confident stepping up replacing the world class Thiago Silva.
Some might have thought of him as a weak point tonight – he was far from it.
Antonio Rudiger – 5
Some dodgy moments from him and guilty of over-playing or having a heavy touch, he was uncomfortable under the high press.
His own goal to put United back in the game was just ridiculous. But he did go a little way to redeem himself in the later stages with some las gasp defensive work.
Reece James – 8
So calm on the ball and under pressure, which he was a lot today.
But James was always an outlet and always used the ball well and looked a threat going forward.
Jorginho – 6
Gave the ball away too often in the first half and was not dealing with United’s high press.
Took his penalty well to put Chelsea back in front.
Mateo Kovacic – 8
Some very great moments from him in deep areas, bringing Chelsea out of danger.
He also looked for the long ball and showed good vision with a few dangerous forward passes.
Ben Chilwell – 6
Some sluggish moments early on in the game but his pass to find Werner for Chelsea’s first half goal was excellent and he grew into it from then on.
Taken off for Alonso on 61 minutes.
Mason Mount – 8
He said he needed to be more clinical in the final third, and he stuck to his words finished off Chelsea’s first half with a great goal.
Mount was his usual lively-self and was a menace to the United back line.
Timo Werner – 7
Was always looking to make things happen and he was very progressive in possession.
Set up Mount superbly for Chelsea’s first half goal, and he also won the penalty for Chelsea’s second goal.
Olivier Giroud – 5
Bit of a spare part through most of the first half and didn’t really look comfortable in the formation dropping deep to collect the ball.
It didn’t really bring out the best of him.
Callum Hudson-Odoi for Giroud (61 mins) – 7
Lively from him as always, he linked up well with James and Mount and was always a threat.
Marcos Alonso for Chilwell (61 mins) – 6
His aerial prescence in both boxes was welcome.
N’Golo Kante for Werner (74 mins) – 6
Did his job well.
