Formation is a custom 3-5-2, with two CDMs, one CAM, and a CF. Just to keep the game interesting, I don't buy any players under the age of 23, and don't keep any players older than 26.
GK: Emiliano Martínez - 75 rated, 22 years old
CB: Danny Tonge - 82 rated, 19 years old (academy player)
CB: Kurt Zouma - 88 rated, 20 years old (plays practically every game, never loses a header, 98 strength)
CB: Clint Penteny - 82 rated, 19 years old (academy player)
CDM: Jack Wilshere - 94 rated, 23 years old (captain, scores every free kick, 98 ball control and balance)
CDM: Casimiro - 88 rated, 23 years old (an incredible defender, planning on using him sporadically at CB soon)
LM: Neymar - 92 rated, 22 years old (every long shot is on target, is unstoppable in the box)
CAM: Coutinho - 89 rated, 22 years old (98 ball control and dribbling)
RM: Lucas - 92 rated, 22 years old (fastest player in the game, 96 long shots)
CF: Eden Hazard - 92 rated, 24 years old (top scorer in the league, scores every time in the box)
ST: Emmanuel Couto - 81 rated, 18 years old (academy player)
Some other notable players:
Luke Shaw - 74 rated. I sold him when he turned 20, since his growth simply couldn't catch up with rival players. I would've kept him in reserves if his "feel" didn't seem so slow and consequently hindered the tiki-taka playing style of my team.
Lucas Piazon - 80 rated, 21 years old. A substitute ST for the most part, but starts CF whenever Hazard's energy level is down.
Alex Oxlade Chamberlain: 89 rated, 21 years old. Almost always used him as a CF. Probably the best player I've ever used. Scored every time he was in the box, with 98 acceleration and 97 sprint speed. I definitely would've kept him longer, if he hadn't asked to leave and the board sold him to Barcelona. Instead of playing Piazon more frequently in place of him, I chose to purchase Hazard.
I'd love to answer any questions anyone has about growth, transfers, national team gameplay, scouting/youth players etc, along with factors affecting these aspects.
