Former Arsenal midfielder Stewart Robson has said that the Gunners must improve their consistency following their 5-2 win over Tottenham Hotspur on Sunday.

Arsenal recovered from 2-0 down to beat their rivals at the Emirates, but Robson has questioned why Arsene Wenger's men cannot perform on a regular basis.

"Arsene Wenger has to realise why they played well. The energy, the effort levels when they wanted to play quickly going forward. They played at a high tempo. When Arsenal do that, they are almost unstoppable," Robson told talkSPORT.

"There's no reason why Arsenal can't play like that every week. Wenger has to get that out of them every week."

Arsenal travel to Liverpool in the Premier League next Saturday.
