No, there's nothing wrong with him, but not great either. He's got the talent of a YA4 player, but he's older and has no natural specials.
You essentially have 3 options:
- Keep him and train him yourself. With your facility levels he'll probably just be about good enough for your current team, but nothing special.
- Treat him as a farm player and sell him once you can get around the max bank value.
- Sell him right away and hope you get a decent price for him.
If you take the 3rd option he might make around the max bank value, saving you the time of farming him.
