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

[LOS ABRANTES FC]

Thank you.

This is the player.

I've tried different configurations of training - 3 different defense drills: no effect. 3 different attack drills: no effect. 6 mixed drills: no effect.

Luca, this player is far from being a fast trainer. At your level a fast trainer is worth between 5,5 ML and 6 ML.
Look at post 579 of the thread i've linked before.
My suggestion is sell and buy another one more expensive...
