Replacing RVP won't be that easy tbh. It's not just his goals that we'd need to replace, but he also assisted quite a few goals as well, so getting a "fox in the box" wouldn't be a like-for-like trade and we'd be losing something upfront if that's what happens.
It's by no means impossible to replace RVP, but we would need to pay top dollar to get the sort of player who would give us everything RVP did, and possibly more.
