Hakim Ziyech and Thiago Silva sunk Spurs early in the second period as Chelsea moved a point off second-placed Liverpool. Harry Kane had a goal ruled out for Tottenham at the end of a feisty first half. Ziyech was outstanding for the Blues, whereas Spurs offered little direct threat after falling behind.
Chelsea ratings
MASON MOUNT - 8
Good work early on to pull back for Lukaku who should have done much better with his effort from just inside the box.
His usual efficient, hard-working and effective self and capped a thoroughly decent display with a real touch of quality when he bent in a lovely free-kick for Silva to glance in for 2-0.
HAKIM ZIYECH (subbed, 90mins) - 9
Bent a wicked ball onto Hudson-Odoi's head with mere minutes on the clock but the winger nodded wide from close range.
Was troublesome throughout as he staked a real claim for a permanent starting spot in Tuchel's team.
And capped his superb performance with an absolutely delicious finish two minutes after half-time.
Received the ball from Hudson-Odoi just off the right-hand corner of the box and bent a left-footed effort beyond the stranded Lloris and into the top-left corner.
I believe they call it 'top-bins'.
Stung Lloris' palms just moments later with a fierce left-footed strike from almost the same position but the Frenchman batted it away.
Standing ovation from the crowd and a huge pat on the back from Tuchel as he came off.
ROMELU LUKAKU - 5
Blazed over a huge chance with his right foot in the opening minutes when Mount put it on a plate for him.
Wasn't massively involved for the rest of the game and looked laboured and predictable when he was.
He held the ball up well on occasion and it's hard to be too harsh on him as Tuchel's system just doesn't involve him that much which means he doesn't see much of the ball and it's always in deep positions when he does.
N'GOLO KANTE (replaced Jorginho) - 6
Came on with the Blues 2-0 up and shut the game down effectively to secure the three points.
MARCOS ALONSO (replaced Hudson-Odoi) - 5
Not enough time to have an impact.
SAUL NIGUEZ (replaced Ziyech) - 5
Not enough time to have an impact.
