1. Bebe
Surely the worst of the lot, Ferguson signed Portuguese forward Bebe on the recommendation of his assistant Carlos Queiroz, having never actually seen him play. The relative unknown still cost United £7million and never managed to break into the first-team, later revealing that he couldn’t understand a lot of what Fergie was saying and that he didn’t take his time at the club very seriously. He is currently out on loan in Portugal and they are unlikely to be able to find someone willing to take him off their hands permanently. It’s bizarre to think one of the greatest managers in the history of the game could make such a poor judgement call.
