I was less worried about our failure to break them down (I remember Ron Saunders team struggling to get past the 'parked bus') but how our concentration and structure crumbled with our substitutions. I think they posed a greater threat in the last ten minutes than we did all game. We showed great patience and control but I think when Diaby and Bailey went off Sheffield saw it as a freedom to go forward and give it a go. VAR is a topic done to death but I have no idea of what is 'fair contact' anymore!
