Maurizio Sarri's unbeaten start to the season came to an end as Chelsea were beaten by Tottenham 3-1 at Wembley.
Spurs were the better team throughout and were well deserving of their victory.
Dele Alli got the north London side off to a fantastic start after he flicked home a Christian Eriksen cross after just eight minutes.
Harry Kane then doubled their lead after 16 minutes to ensure they held a two goal lead going into half-time.
And Heung-Min Song produced a quite brilliant solo effort just after half-time to give Spurs an unassailable lead.
Olivier Giroud got one back for Chelsea with five minutes to go but it was too little, too late for the away side.
Tottenham have now leapfrogged Chelsea into third place following the victory.
While it was a great day for Tottenham, it was an extremely poor day for Chelsea.
They were second best all over the pitch as Tottenham ran riot.
Jorginho, Chelsea's marquee summer signing, also had a poor game.
He struggled to impose himself and was completely ruined for pace by Son during his brilliant third goal.
Gary Lineker could not help tweeting about the Italian during the game and, it must be said he made a valid point about the former Napoli man.
The Italian was brought in by Sarri and was immediately put in N'Golo Kante's role as defensive midfield.
In order to accommodate Jorginho, Kante, who many consider to be the best defensive midfielder in the world, has been moved to the right wing.
And Lineker tweeted in the second half how he could not believe that this has been allowed to happen.
He wrote: "Son just ran away from Jorginho. So baffling to see him playing in the position of the world’s greatest holding player, whilst Kanté plays on the right."
Well said, Gary.
Jorginho is a good player, that's got to be said.
But if Kante was in Jorginho's shoes in that situation, there is no way that Son is scoring that goal.
It's baffling that Sarri is deciding to put Kante in an unnatural position where he is no where near as effective.
While he is still performing well, Chelsea are missing out by deploying the world's best defensive midfielder on the wing.
And many Chelsea fans were all agreeing with Lineker that Kante needs to return to his natural in place of Jorginho.
