My ST made me eat my words. He just scored 4 goals and made 2 assists, lol. As for my AML, he just gained a star (120 %) after becoming MoM and scoring 3 goals.
However, if I wanted to turn him into a striker it would be an easy task as I'd target his grey skills which are around 70 %. So he would gain a new position pretty quickly. I have other plans for my rest packs though as I plan to add another FT to my back line. Didn't think it would be possible, but my current FTs (5) made it to 120 % q + an added SA with ~450 rest packs. Thought it would require more, but now I have the resources for another FT instead.
