Manchester United to be questioned by Portuguese police over transfer of Bébé from Vitoria Guimaraes Bébé, 21, joined United in August 2010 for a transfer fee of €9 million after playing for just one season in the third division. The forward has subsequently started just two games and made four substitute appearances for United before he was sent on loan to Turkish side Besiktas. An anti-corruption unit based in the Justice Ministry in Lisbon is now investigating the transfer from which his agent Jorge Mendes made €3.6m from the deal, it has been reported in the Guardian. Mendes, who also looks after Cristiano Ronaldo, Nani and Anderson, became the forward's agent just days before his transfer to Old Trafford following a dispute with Bébé's former agent Goncalo Reis. Reis has previously formally complained to the Portuguese Football Federation that Mendes poached the player off him shortly before his big-money move. While United will be part of the investigation there is no suggestion that the club have done any wrongdoing. A spokesman for United said: "Clearly if the police ask us for information, we will co-operate with them. Nobody is suggesting that we have done anything wrong.
