Leandro Trossard opened the scoring before Kai Havertz and Ben White each bagged a brace.
The result sent Arsenal three points clear at the top of the table.
And it also their biggest Premier League win over Chelsea, who remain stuck in ninth place.
At the final whistle, Gunners fans wildly celebrated the victory.
Some set off fireworks, much to the annoyance of Joe Cole.
While others settled for a dance in the stands, with one couple catching the eye.
But it wasn’t just supporters who were in the mood for a boogie as Shakira’s hit song ‘Waka Waka’ blared from the speakers.
Odegaard’s girlfriend Helene Spilling, who is also from Norway, delighted onlookers as she grooved to the post-match music.
The 27-year-old and Odegaard, 25, are believed to have been dating for just over a year after they were first spotted together at the London Football Awards in March 2023.
Helene rose to fame in Norway’s version of Strictly Come Dancing, which she won in 2021.
The model and pro dancer boasts 141,000 followers on Instagram.
And supporters were delighted with her latest moves in the Emirates stands.
One said: “Odegaard winning on and off the pitch.”
Another declared: “Wow love it.”
One noted: “As long as she is happy we’re all good.”
Another added: “I’m the happiest man today.”
