I think we are mostly all agreed on the need to replace/upgrade Hutton, however to find one that is great at defending, runs up and down the line and has a good cross/end attacking product could prove very difficult and may be the reason we don't yet have one.
It would be alot easier to get a solid defensive right back but with how we are playing the full backs are our width. It is potentially the hardest position to fill.
Maybe Amavi has a brother or something...
