Arsenal striker Gabriel Jesus celebrates scoring after a slip-up from Tottenham keeper Hugo Lloris
Arsenal remain top of the English Premier League after a convincing derby win.
The 13-time champion defeated his eternal archrival Tottenham Hotspur 3-1 (1-1) in a duel for football power in north London on Saturday.
It was the seventh league home win in a row.
With 21 points from eight games, the Gunners will not be ousted even if Manchester City wins the city derby against United on Sunday (3 p.m. TV: Sky).
The champions with former Dortmund star striker Erling Haaland would then have 20 points in their account.
The previously unbeaten Spurs (17) could have overtaken Arsenal, but thanks to Harry Kane (31', penalty kick) they only lasted until the half-time break.
Thomas Partey (20th) had given the hosts the lead.
Arsenal's Gabriel Jesus (49') and Granit Xhaka (67') scored in the second half.
Before Arsenal's second goal, Tottenham keeper Hugo Lloris made a mistake.
Tottenham's Emerson saw red after a nasty kick on his opponent's ankle (62').
Despite the bankruptcy, it was a record game for Kane.
The Englishman became the first player to score 100 away goals in the Premier League.
