I beg to differ. I thought that Bunney was a liability at left back and can only recall perhaps 2 decent games he had for us. He got hopelessly skinned more times than I care to remember. Buchannan may not be League 1 level and needed competition but Bunney was definitely a step backwards. Maybe he could become a useful winger?
Backs get skinned, that's the opponent's wingers job, but I don't remember him being that bad in defensive duties, certainly not hopeless and he had plenty of pace. For me it was his final ball that let him down, to many passes going astray and overhit crosses.
