The Gunners headed into their clash in Munich coming off the back of four successive Premier League victories and of course a morale-boosting 2-0 win over Bayern at the Emirates.
Despite the absences of Laurent Koscielny and Hector Bellerin, there was genuine belief that that Wenger’s side could cause Bayern problems and gain a positive result at the Allianz Arena.
However, an early goal from Robert Lewandowski set the tone for a dominating display from the hosts and Arsenal throughout were left far too open and slack in defensive organisation.
Co-commentating on BBC Radio Five Live, Lawrenson cursed the visitors’ defending, saying:
“How many times has a Bayern Munich player got round the back and in behind the Arsenal defence? Arsenal's full-backs had little or no protection, that is where all the chances came from,” he said.
“That is where Bayern Munich got in. You cannot give a team so much width and not expect them to create so many chances. Against the top teams, you cannot have one weakness, they will keep exposing it.”
Aside from Lewandowski's strike, Thomas Muller netted twice, David Alaba crashed in a wonderful 25-yard strike while Arjen Robben scored within a minute of coming on as a substitute.
The way Bayern’s full-backs Philippe Lahm and David Alaba pushed up throughout left Arsenal’s fullbacks exposed to two vs one situations – a tactic the hosts repeated on a number of occasions.
Alexis Sanchez and Joel Campbell were tasked with dropping back and helping out, yet with only four tackles between them it was evident they weren’t disciplined enough to carry out their duties.
Arsenal's hopes of qualification now hinders on beating Dinamo Zagreb and then Olympiakos in Greece by a minumin of two goals, not an impossible task but a tall order indeed.
