If his shots have really curl than he should have something about 75. Free Kick would be 65, normally standard for strikers. I wouldn't go for *Scoring, with his actual shooting values he can score good enough.
Changed his stamina from 80 to 82. He really got a very good stamina, runs and runs every game. That's for sure one of the main reasons why every Nuremberg-coach has backed on him though he barely scored.
Also changed his mentality from 74 to 76 for the same reason. He got a strong mentality.
