2. Bebe
Tiago Manuel Dias Correia, or "Bebe" as he is mononymously known, was so unheard of when he joined United in 2010 that even manager Sir Alex Ferguson admitted he had
never seen him play before signing him up. The Portugal international was signed on the advice of former United assistant Carlos Queiroz, but Fergie might have benefited from sticking on a DVD of the then-20-year-old in action before opening his wallet, because he's been awful. Fans wondering what the legendary Scot had ever seen in Bebe are still waiting for the answer to that question with the former Estrela man failing to settle down at Old Trafford in the three seasons since his move. Bebe has been loaned out three times since 2011, to Beikta, Rio Ave and, earlier this summer, to Paços de Ferreira. One has to wonder how much longer it will be before United finally cut all ties with the flop, who has never scored for the Reds and has netted only twice during his three loan spells.
