Sunderland would rely heavily on Defoe. 14 goals at present.
As for Grimsby, we would be fine so far with Bogle getting the majority of our goals but he's gone now and the rest of the team have hardly scored. Our team is mostly English though so.
Depends on whether you include English players who chose to represent other countries. If you don't, we'd be a lot lower because Lyle Taylor is a Montserrat international.
Well the homegrown player rule at the moment is something like the player has to be at a club in England for a few years before the age of 21 which seems silly as Cesc Fabregas counts as homegrown for example.
