Since we're all weighing in I thought I'd give my take as well.
I think it's quite telling that Kelly plays CB for England, consistently. He's always been one of the best in that position, and though we lack cover for RB I still think he'll eventually move to the centre. Perhaps McLaughlin, in 2 years, will be ready for the position of covering Glen Johnson, but between the playing in the centre for his country and the fact that we've been linked with several versatile players who play RB/RW/CM, I think that we're also looking at possibly moving him inside, at least part time, this season.
