I think having a new keeper who is at least semi competent may have something to do with things as well.
Matt Sells Seashells oozes quiet confidence and, whilst maybe not a world beater, does what he needs to with little fuss. This give confidence to the center backs they now believe that they don't have to be ready to bail the keeper out. Because of this our center mids can concentrate on doing their job of winning the ball back and moving it forward without having to consider the need to drop back to cover for a center back who's had to drop back to cover the keeper.
All of a sudden we are playing slightly higher up the pitch, keeping shape and looking like we actually belong in the EPL.
I think we should (injuries not withstanding) keep things as they are for now and Sangare will have to win a starting place back from bench.
For all that WHAM are struggling at the moment, they are 8th in the league and won a European trophy last season. We beat them relatively comfortably and it's as good a barometer of what we are capable of as anything we've seen so far this season.
