I want to put him as winger. Should I retrain him to left ou rigth side? He is competent at AMR and AML, and he is rigth footed.

I only need to retrain the position one time or I'll have to be always retrain him to winger?

If he's fully trained up as an AMR, and you keep playing him there, then he'll stay accomplished in that position.

I don't know exactly what Agbonlahor's versatility is rated at so if you start playing him as a striker instead for a while, he might start to lose his rating for AMR.
