Arsenal went five points clear at the top of the table after a second-half demolition of Tottenham, with a brace each from new-signings Viktor Gyökeres and Eberechi Eze.
There was no new-manager bounce for Igor Tudor, as his Spurs side remain winless in the league in 2026 and just four points clear of the relegation places.
In front of a raucous crowd, it was the visitors who took the lead through Eze's acrobatic finish from close range. But they were ahead for only a couple of minutes after a rare Declan Rice error gifted Spurs a way back in through Randal Kolo Muani's goal.
Gyökeres lashed home from outside the box early into the second half to restore Arsenal's advantage before Eze scored his fifth goal of the season against Spurs near the hour-mark. In between the two goals, Kolo Muani had the ball in the back of the net but saw it ruled out for offside.
Spurs struggled to force their way back into the game, and Gyökeres added further gloss to the win with a well-taken goal in added time.
