Tottenham 1 Arsenal 3: Stunning goals from Cesc Fabregas and Emmanuel Adebayor earned Arsenal victory at White Hart Lane and piled on the misery for Tottenham manager Martin Jol.
Spurs had been ahead in the 15th minute through Gareth Bale's free-kick and had chances to add to their lead before Adebayor levelled.
Fabregas' strike came with 10 minutes remaining, and Adebayor also found the top corner in stoppage time, leaving Spurs with still just one Premier League victory this season.
It was a cruel blow for Jol, who has appeared undermined by his board this season after the infamous meeting with Sevilla coach Juande Ramos.
Bale's free-kicks at the start of last season helped him establish himself as one of the brightest talents around, and his set-piece in the 15th minute was an example of his accuracy.
He curled the effort behind Arsenal's wall and inside Manuel Almunia's near post, leaving the peroxide Spaniard fuming with himself.
The 18-year-old, with two goals in his first three Spurs matches, was playing on the left of midfield to give Jol's side balance — but he was also needed to defend as Arsenal attempted to drag themselves level.
Adebayor immediately threatened at the other end after the opener, with Robinson required to turn his volley around the post.
With both sides attacking, possession switched frequently and tackles flew in, Jermaine Jenas picked up a yellow card for one of them on Van Persie. Pascal Chimbonda was fouled in stoppage time but was booked himself for urging referee Mark Clattenburg to show his opponent a yellow card.
As expected, Spurs were forced to defend early in the second half, although Berbatov should have added a second goal in the 51st minute. Steed Malbranque slipped the Bulgaria striker through and he rounded Almunia but could not do the same to Kolo Toure, who was the last defender.
Gunners boss Arsene Wenger then brought Tomas Rosicky on for Diaby to give his side another attacking dimension.
Yet Spurs were still threatening a second goal, with Younes Kaboul heading over and Tom Huddlestone cracking a trademark volley wide from Chimbonda's cross.
Jol has been frustrated with Spurs' defending from set-pieces this season and a free-kick was their undoing again, with Arsenal levelling in the 65th minute. Adebayor nipped ahead of Robinson to meet Fabregas's free-kick after Malbranque had fouled Mathieu Flamini.
Fabregas then got his stunning goal, receiving the pass from Rosicky before taking aim from 30 yards and bending into the top corner with the outside of his boot.
Darren Bent came on and was sent through but the striker missed his kick. Adebayor's volley came in stoppage time to add to Spurs' misery.
