Sir Alex Ferguson broke his No.1 transfer rule at Manchester United when he signed Bebe without ever watching him play.
The Scot always watched potential arrivals before making a move, but chose not to when he paid £7.4m to sign the forward. The Portuguese had been playing in the third tier in his homeland before Vitoria de Guimaraes signed him in 2010.
Bebe continued to impress in pre-season and, before playing a competitive game, United came in with a bid as they knew Benfica and Real Madrid were circling. Ferguson's assistant at the time, Carlos Queiroz, advised the Scot to sign the forward.
