delph, i'll maybe give you injury prone, but he was intended a squad filler rather than a starter i reckon, and on paper he was a good shout. experience, coming from a winning team, versatile in terms of positions, and on a free. i was happy when we signed him. less so since, obviously.
mina and gbamin - no injury record prior that i'm aware of, and gbamin's was basically a complete freak injury. now we've got a player who hasn't played in a couple of years trying to slot into a dysfunctional team. i wouldn't give him a cat in hell's chance of being able to pick up where he left off.
in hindsight, they've not really worked out - although mina is still our best defender when he plays so he's hardly a failed signing. is he good enough for where we want to be? arguably not - but then there are few players in the team at that level if you ask me, so singling him out is a shade unfair.
