Missing Player

Yesterday, I bought a 5 star striker named Duan. I was excited to use the lad to find out, he went missing. I check notifications and the morning assessments. All it said is that I had bought the player and nothing else. I wish to get this solved, missing out on a big player.

you must have an empty place in your team.
So, less than 22 players.
Try to keep an empty place for him and maybe you 'll see him back in your squad.

I only have 18 players. I made sure before I even started buying players to have less than 22 in the squad.
