I think it's completely legit if your scout found him.
I realize it's probably early in your save (because the guy we're talking about IS 38, I think

), but don't forget that as things progress you will see things that seem unlike real life, because your save game splits from real life as soon as you start it and evolves differently. I once had a guy who was a Premiership player IRL on trial at a Conference club and decided not to sign him. It wasn't unrealistic in my game -- he was crap in my game.
In my current save, eight seasons in, Liverpool has just been relegated and Birmingham just won the Champions League.
