Maybe I've rattled on about this before, but why do we need to sign someone when we have an option on the books?

My memory or insight may be failing me, but what were the circumstances of Scott Carson's on-loan departure? Too expensive? Lost it? Fell out with the then administration? I genuinely don't know.

I've just been looking down the free agent list and only Jo Hart at his best is (arguably) is in the same league as SC at HIS best, and he'd no doubt cost more.

Anyone?
