Future stars evolutions

Hi. I’ve just completed Nwaneri evolutions but i didn’t know i had to add the weak foot upgrade before completing the icon Nwaneri 91. Please somebody tell me that it’s possible to add it anyway. I buy this game since 2011 and it seems absurd that it doesn’t say that i had to add the weake foot upagrade before completing Nwaneri. I hope there is a solution because a player 4-3 is unusable. Thanks regardless.
