The MR Youth-Academy kid I got that I turned into a wing-back with the Shadow-Striker Ability made his real debut today, scored two goals on long-shots and the Shadow-Striker symbol showed both times! Haha I was as happy as a kid on Christmas when I saw that lol. Overall I am starting to see these signs more and more, I think a problem is that on my iPhone (on which I watch most games on), the blinking goal sign covers a big part of the field and if the SS or PM sign show after I scored a goal its often covered by the sign.
