I just found that out myself. I bough an attcking MC, dribbler with a difference of 18 vs def and 12 vs physical on attack. I thought he migh be usefull as a central MC with red arrows, functioning like a AMC. Against much weaker opponents he does fabulous but if quality nears mine, he goes under. Since I bought hime, I only assigned sp to physical, but I fear now that I might get better players for the money I get from selling him. He's top level 5*.
