Ex-Arsenal star Paul Merson heavily criticised Tottenham boss Antonio Conte for not changing his tactics during Spurs' woeful first-half performance in the north London derby on Sunday.
An own goal from Hugo Lloris and a long-range effort from Martin Odegaard put Arsenal 2-0 ahead against Spurs at half-time, as Mikel Arteta's side dominated their north London rivals.
The Gunners came into the heated derby with extra motivation, knowing that a win would put them eight points clear at the summit of the Premier League after Manchester City's 2-1 defeat by Manchester United on Saturday.
