Martin Keown believes Arsenal's 6-0 victory against Lens has 'laid down a marker' for other teams across Europe.
The Gunners will advance to the knockout stages of the Champions League with a game to spare, having only lost one game in their European campaign so far.
They started brightly in the match with five different players getting on the scoresheet inside 27 minutes, with Kai Havertz opening their goal account with his second goal in consecutive matches.
After the match, former Gunners defender Keown lauded their younger stars claiming the north London side showcased the quality of the English first division.
