Always it's the very repetitive question and no specific answers ... but I can tell you that nothing is certain to be used to bring your player performance.

but i can advice you with the following :

1- If he is playing lonely in attack ----> so try to add someone beside him.
2- If he is playing beside two/one striker ----> make him play alone or change his place from right to left to the mid .
3- Put red arrows on him or remove the arrow or put blue arrow or remove just make any change.
4- Put him outside for 2 or 3 matches ... then make him play one half and then make him play one match.
