I'd mix it up vs Arsenal. They're expecting a floaty 4-3-3 so I'd sock e'm with a narrow 4-4-2 / 4-4-1-1 like this...
------------------------------Mignolet-----------------------------
Clyne------------Toure-----------------Sakho----------Smith
Milner-------------Can---------------Henderson------Moreno
----------------Lallana/Firmino----------------------------------
----------------------------------Benteke--------------------------
We'd be strong / high energy down the flanks with plenty scope for overlapping full-backs. Both full-backs and wide midfielders are capable of decent crosses so a chance to make the most of Benteke's supposed strengths. He'd benefit too of having a strike partner/support to pick up knock downs etc. Ibe to come on for last 30 minutes and Texeira another late option for the 2nd striker role.
