It was not a great afternoon for Tottenham and Jose Mourinho.
A 2-0 home loss against rivals Chelsea means that they are now six points adrift of the Blues in the table.
A brace from Willian, one coming from the penalty spot after a rush of blood to goalkeeper Paulo Gazzaniga's head, was enough to see Chelsea take all three points from the game.
Things got worse for Spurs too, when VAR intervened to advise referee Anthony Taylor to show forward Son Heung-min a red card after he kicked out at Chelsea defender Antonio Rudiger.
But how did the players perform on a day that Spurs fans would prefer to forget? Take a look at football.london's player ratings below to find out.
Paulo Gazzaniga
What was he doing? A goalkeeper who decided to kung fu kick and miss a ball instead of catching or punching it away. Couldn't do much about Willian's opener but he had a shocker with that moment before half-time. Fortunate that Abraham was offside as well when he pushed an Alonso shot into his path. 3
Serge Aurier
Looking the other way when Willian took his short corner and was too slow to close his run and shot down. He had conceded the corner in the first place. For long periods this was back to Aurier at his worst, out of position, slow to get back and little quality when he did get the ball in attacking areas. 3
Toby Alderweireld
The Belgian was probably Spurs' best defender on the day and despite the scoreline, Chelsea didn't have many shots on goal. He did stop a goalbound Reece James effort late on. 6
Davinson Sanchez
So panicky in possession. Some decent moments in defending but at times it was making up for his own errors. 4
Jan Vertonghen
Struggled at times down the left. Not one of his finest performances and he was hooked for Rose in the second half. 5
Eric Dier
His passing was poor and he was leaden footed as Chelsea burst past him. Didn't emerge for the second half. 4
Moussa Sissoko
Picked up a knock in the first half and it seemed to affect his rhythm at times. 5
Dele Alli
Along with this fellow attacking midfielders this was a performance to forget, or better to learn from. Poor in possession as Spurs missed his creativity. 4
Son Heung-min
Fired over on the half hour mark. Struggled to find his rhythm and his red card was just plain stupidity. It's not the first time he's lashed out and while Rudiger made the most of it there was zero reason to kick out at the Chelsea man. 1
Lucas Moura
Struggled to control the ball when Spurs needed him to and played his part in not concentrating with the short corner leading to Willian's opener. Offered little before being replaced by Ndombele. 3
Harry Kane
Swept over Spurs' first effort at goal on 27 minutes. Barely saw the ball from then on as he registered Tottenham's first shot on target in added time. 3

Subs
Christian Eriksen
Added some forward movement to Spurs' play but his set pieces was atrocious, often barely beating the first man. 5
Danny Rose
Replaced Vertonghen in the final 15 minutes but brought little to the party. 4
Tanguy Ndombele
Offered a bit of thrust to Tottenham's game but it wasn't enough. 4
