I have the same problem. I didn't know who to pick for the evolution until this weekend after I had finished my weekend league and figured this was ok because you only need to play 5 games with my player (kante) in the starting 11. The problem is that objective is bugged. I played the first game with him in my starting 11 but then subbed him out because he has low stamina and the game didnt count. So I am also screwed and I think EA should extend it until the end of this following champs especially because this weekend is still under the immortal promo!? Why make the objectives for the evo end before the season and immortality evo expires. Sometimes EA is so stupid.
