I accidentally exchanged my TOTY evolutions 85 cannavaro

This has also happened to me we should have received a warning that we could not get this player back if we traded it Away. We should have been informed that we need the 85 rated player to exchange for the next evolution in my case I used my Rivaldo in an exchange and had no awareness of I needing to use for the next evolution I spent a lot of gems and played alot to grind out 15 games and I think the rest of the people who have faced this problem should have felt the same I think we deserve a warning and an extra 85 player for the people who have lost their player to exchange for the evolution I hope ea would take this into consideration and many people might not have watched the livestream in the toty event so please take this into consideration as I really need him for my team and if ea doesn't do anything about his I think there is no reason to play this event anymore
