I kinda miss having 4 at the back, but really can't complain. But what worries with our current 3-5-2 are the wingbacks. Sure Litch is WC and Asamoah is defensively solid, but how will they cope with being bombarded by a quality winger supported by a quality fullback that has yet to happen, when the play is streched out enough I think we'd have a significant amount of issues, in Serie A we haven't faced such an issue yet neither have we had to deal with that in the CL yet but I'd be terrified by a Lahm-Ribery/Robben or anything that has half that quality.
