Johnson is woeful.
If we get a LB who is Solid in the air (hopefully, equally capable in other abilities required off a left-back as well), we should be ok.
Few years ago Wenger called us a basketball team, when we fielded Crouch, Cisse, Hyypia, Momo Sissoko, Gerrard, Carragher, Riise, Kewell, Finann, Kuyt, and Reina
Kewell was probably the shortest of the lot, and he was quite good in the air....otherwise that team was quite shite.
