Chelsea registered their fourth win in all competitions this season – and third in January alone – over London rivals Tottenham with a 2-0 triumph at Stamford Bridge.
Harry Kane thought he had struck first before the break but a slight push on Thiago Silva saw his finish ruled out before Hakim Ziyech expertly curled in his fifth league goal for Chelsea – all five of those having come at different venues.
Silva added a second soon after as he became the oldest player (37 years, 123 days) to score in the Premier League since February 2013 to condemn Antonio Conte to his first top-flight defeat as Spurs head coach.
The defender's header was set up by a free-kick from Mason Mount, who provided his 20th assist since the start of the 2019-20 campaign – the most by any Chelsea player across all competitions in that period.
Spurs were unable to breach the Blues' goal, meaning they have now gone six matches across all competitions since last scoring against Chelsea, who became the first side to collect 500 points in Premier League London derby matches (501 points from 272 derbies).
