Goals scored in penalty shootouts never count, and for good reasons. Those goals are not based on performance, and the chance is "awarded" automatically when extra time finishes with a draw.
But penalties in normal time do count and they're essentially the same. I suppose it's something that can't be 100% consistent but I definitely agree that shootout goals shouldn't count.
Penalties in normal time are not given out automatically. It is earned, at least in theory. A team needs to have conducted an attack worthy of being irregularly stopped by the opponent's defense in order to be awarded a penalty.
Feeling the burn of the Euro loss? Actually given that they currently have two of their top scorers from this list (plus Rashford and Welbeck who are still active on 12 and 16 respectively) they are about average. Not quite as good 2005-2008 (according to this list) where they had 7 of their top scorers granted but they did just get to the first ever Euro final.
I know f.a. about English football, and not much about the sport in general, but all the sources I checked listed Camsell as having 18 goals, which would put him right in there with Dean, Haynes and Hunt.
