This is my player Ludovic. I am training him AML position so that he can score more goals and assists. But since he was originally an AMC and then I trained him Striker his crossing stat is very low.

Since I am planning to use him as an AML in next season, I want to increase his crossing as it's a very important attribute for AML.

Guys suggest me the best drill to do so. I don't wanna increase his defensive attribute.
