Miazga is not in the game by default..the best way to create him is by using a free agent with a real ID & then relinking the face to that ID by changing the "xxxxx" in the folder structure to the ID you are going to use.A good player to use right now is Adam Johnson who has been sacked by Sunderland and will probably not return to the game for some time...so make Miazga over Johnson & relink face to ID 32677.
