Tottenham sunk to a third consecutive league defeat as Jorginho’s penalty was enough to seal all three points for Chelsea.
Thomas Tuchel masterminded a richly deserved victory in his first London derby as mighty Chelsea smashed Tottenham 1-0 to climb above them in the Premier League.
Jose Mourinho could look on only in the pouring rain at Tottenham Hotspur Stadium as the lackluster Spurs were bossed by his former side, which slipped to a third consecutive defeat.
Jorginho’s first-half penalty, without conceding a goal for Chelsea under Tuchel, scored seven points from three matches, bringing them to sixth place.
After another lackluster outcome, Toothless Tottenham dropped down to eighth, being outclassed and fortunate not to suffer a more emphatic defeat.
Timo Werner almost got Chelsea off to a dream start when he nodded along with Cesar Azpilicueta ball in the first minute, just short of it.
The Blues kicked the ball around with a swagger and deservedly took the lead 24 minutes in, Jorginho finding the bottom-right corner of Hugo Lloris’s net from the spot after the lively Werner had tripped Eric Dier.
Andreas Christensen replaced the injured Thiago Silva as Tuchel’s side started to dominate, although Serge Aurier missed a chance to equalize late in the first half as he headed Son Heung-free-kick min’s wide.
Spurs showed more strength after the break, driving Chelsea higher up the pitch, while as the far post drilled deep, Callum Hudson-Odoi should have doubled the lead.
Aurier made a brilliant last-ditch tackle to prevent Werner from breaking his Premier League goal drought, as Germany’s striker was about to pull the trigger after being set up by Mason Mount.
Lloris bravely punched away a dangerous cross with Christian Pulisic waiting to pounce and Mateo Kovacic poked a shot high with Chelsea firmly in charge.
The excellent Mount was denied by a strong reflex save by Lloris as Spurs opened up all too easily again before Edouard Mendy was finally called into action, palming away Erik Lamela’s shot with just over 10 minutes to go.
Carlos Vinicius should have made Chelsea pay for their profligacy, but he headed wide from close range late in his first league start, as Gareth Bale was an unused substitute for the hosts.
