Just something to add if you are stuck on the attacking scenarios skill challenge.
I went to customise, create player, created a goalkeeeper who was 4'11, downgraded all of his stats and put him in my rival team (Bohemians for me).
I then went to customise, team sheets, Bohemians/Your rival team, clicked their default formation and added my newly created goalkeeper in place of the starting keeper.
When I went to play the skill challenge, the short goalkeeper was now in goal. (Gave him gold headgear so I knew it was him)
Challenge was still a pain, but I feel that this helped a bit when shooting from distance. Just got it with 20500 points.
