If you are looking for goals that we don't sort of deserve, it's of course some stupid pens stupid defenders have given us but also the set pieces.
A set piece can always result in a goal being scored (such as yesterday's Brighton equalizer when they had in fact almost given up the ghost) and we have scored many such.
I 'm afraid we are clueless when it comes to opening up defenses, apart from some heroics performed by Lukaku. Without the Germans it gets even worse.
