I don't think he's good enough in physical duels to play next to anybody but Fabinho in a double-pivot, but I think we get the best out of him as a #8.
@MattAldridge31 <25%. Obviously you have cases of more efficient penalty takers, like Lampard, and more efficient goalkeepers like Diego Alves, but across the board there's a pretty big chance you'll score regardless.
Speaking more to the point of devaluing pens somewhat, than Lampard.
