Hasn't played LB against fast wingers this season either. However much you love him and however lovely he is he WILL be targeted as our weak link by any team with pace on the wings.
On top of which he is not a left back either.
Guess or inside info? If this injury is bad would it be overreacting to suggest it could derail our season until a replacement can be found in January? Calde is a lovely bloke but he is not good enough to be LB for a table topping team...IMO.
