Smalling Jones and Varane, if all are as versatile across the back 4 as suggested, I can see playing as a 3 at the back in future against crap teams. Sometimes i really do wonder why we need 4 at the back against the west broms, birminghams and wolves's of this world. We generally only concede from set plays against poor teams, and then it would mean were likely to score more.
Bit of a drastic point from me I suppose, but anyone else think the same? Like I say, really don't see the point of 4 at the back against teams with 8/9 behind the ball.
