Help! My 6-stars 18yo striker is super slow at training

[pele]

Hi! I just bought a new 18yo striker (6 stars). I assigned him a new special ability (1-on-1 scoring).

He is now super slow at training it. I've both tried defensive-hard and attacking-hard trainings.

I now stopped the training of the special ability. Since I did that, my player did not gain any single ability point from the last 3 games it played.

Is it normal? Am I doing something wrong?

Thank you in advance.

From my observations, 1 SA point = 16-18% training for an 18-year-old. Training type doesn't matter.
For a 40 point SA, you should be looking at spending around 50-55 greens.

However, I've heard of veteran players saying that there are players that are super fast trainers and slow trainers.
