Arsenal punished London rivals Tottenham Hotspur at the Emirates Stadium with goals from Thomas Partey, Gabriel Jesus and Granit Xhaka sealing a 3-1 win to keep them top of the Premier League on Saturday.
Harry Kane's leveller for Tottenham saw him set yet more scoring records, but his side self-destructed after halftime as their 12-year wait for a league win in the fixture continued.
Mikel Arteta's Arsenal have now won seven of their opening eight games and lead the standings by four points with second-placed Manchester City facing Manchester United on Sunday.
An absorbing derby was evenly poised after Partey's sublime 20th minute opener was cancelled out by Kane's penalty just past the half-hour mark - making him the first player to score 100 away goals in the Premier League.
But Arsenal were gifted back the lead in the 49th minute when a dreadful mix-up between Spurs goalkeeper Hugo Lloris and defender Cristian Romero allowed Jesus the easiest of tap-ins.
Emerson Royal was then red-carded for the visitors in the 62nd minute for a needless kick out at Gabriel Martinelli deep in Arsenal's half, and five minutes later Xhaka swept in Arsenal's third to leave Tottenham reeling.
