With the adjusted criteria:
Bunn
Beye Senderos Baker Shorey
El Ahmadi Sylla Sanchez
Holman Hogan Richardson
I know a few of them didn't play all that often but all of them were signed with the intention of being regulars and the ones who didn't manage that were so shit that we either spent again to replace them or played people out of position in their place. I can accept that I'm probably being a little harsh on El Ahmadi but, for me, having him in our midfield after the likes of Barry, Milner and Delph is the point where the hope under Lerner really died. Baker might also be harsh but if he hadn't come through our academy he'd probably have struggled to have a career much above League 1, that he played well over 100 times for us shows just how far we'd fallen by the time we got relegated.
Think some of them were more huge disappointments rather than worst ever. Beye and Shorey were decent enough mid table prem full backs when we got both in but neither were much good for us under MON and became expensive wage drains.
From memory didn't Senderos play about five games with Vlaar in which we kept 3-4 clean sheets then picked up an injury and was never seen again? I can remember him being brilliant away to Liverpool so that's a surprising one.
Never ever rated Clark as a CB. He was a bit like Ridgwell, always had an error in him at key point in game and we conceded a huge amount from corners when he was a regular.
