A hitherto unstoppable force meets the Premier League's immovable object as Chelsea travel east to face Arsenal at the Emirates, and you can follow it all live right here, with ESPN.
With both sides coming into the game having claimed maximum points from their first two outings, something will have to give this afternoon.
After defeating Manchester City in impressive fashion in the Community Shield, Arsenal got off to the perfect starting in the opening game of this Premier League season when they swatted aside Coventry City.
It was a set of familiar faces who got on the scoresheet that day, with Kai Havertz, Bukayo Saka and Martin Ødegaard providing the goals.
Saka proved the hero a week later as the Gunners eventually overcame a stubborn Aston Villa defence to take an impressive three points away from Villa Park, even if Unai Emery's much-changed side have made a slow start to the season.
Chelsea come into Sunday's game having already scored six Premier League goals this season. They began their campaign with a trip to another of the capital's teams, beating west London rivals Fulham 3-2 thanks to goals from João Pedro, Morgan Rogers and the revitalised Cole Palmer.
Their second game was even more free-scoring, as Romeo Lavia, Pedro Neto and Pedro again gave Xabi Alonso's side a 3-0 lead against Brighton, only for the game to finish 4-3, with Palmer again getting the decisive goal.
Sunday's game will go a long way to determining whether Chelsea's backline, boosted by the arrival of Emiliano Martínez, can prove as impressive as their forward one.
