Derby didn't give Chesterfield a lot in the first place 5,700 isn't really a lot. Derby gave Southport 7,000 in the last round and Chesterfield could have sold 8,000-9,000 for this match easily. There's also a lot of interest from people who don't support Chesterfield or Derby, so armchair supporters who support the likes of United, Liverpool, City etc have probably got tickets when actual fans will miss out.
