3. Shore up the left flank
Arsenal were torn apart time and again by Bayern Munich over the two legs despite the respectable scoreline, and much of it was down their left flank. With Santi Cazorla playing out there, there was inadequate cover for the left fullback. This was exploited by Arjen Robben and Philip Lahm/ Rafinha who doubled up on the left back to exploit this weakness.
Chelsea too might employ similar tactics against the Gunners and in Andre Shurrle and Branislav Ivanovic, they have two players who have the pace and strength to exploit this weakness in the Arsenal armor. Wenger will have to ensure that the left flank does not become his Achilles’ heel once again.
