I know Lloyd got us to the play off final, but he signed a few donkeys as well as a few heroes. I know Gus has signed a couple of questionable players, but I would say Gus is a far better manager/coach purely for the way he has got the the team to play and find the new players to compliment that style.
Questionable players? Whilst Poyet has signed some absolute gems he's had his fair share of duds, Holroyd and Harley for starters.
