Not all strikers make good penalty takers.
1993. Romania. Bodin.
We had a front four of Rush, Saunders, Hughes and Giggs. None of them were regular penalty takers at the time. Saunders became a penalty taker for Villa. Our most experienced and best penalty taker at the time was Bodin.
I don't think it matters that much where you play. Didn't Paraguay have a keeper who scored loads of penalties for them at international level?
