It's probably not the best choice but I highly recommend a player called Paulinho (not the one who plays for Corinthians).
I think he should be playing for Córdoba CF at the moment in the second division spanish league. He should be around 18 or 19 if your early in your save.
He was fantastic for me at Leyton Orient and won the Premier League and Champions League with me. I sold him eventually but he was my captain for many years.
