Agree i would like to see bernard there,also i watched williams a few times at bolton last season my mate is a season ticket holder and they do bring a friend 4 free games, he impressed me at that level.He deffo has a bit about him.
Now's the time to try Bernard in the role during pre-season I guess
That being said, Siggy can play out wide too so they could switch positions during a match if Bernard could get Siggy's role down, which would give us something different to try from a tactical perspective, especially if Bernard is struggling with a particular right back on a physical level and coming in centrally will help him get into the game more whilst the bigger Siggurdsson can handle the defender
