Manchester United boss Sir Alex Ferguson will boost his defensive midfield options by raiding Real Madrid. Marca says Ferguson intends to sign one of the Diarra's, either former Chelsea and Arsenal midfielder Lassana, or Mali international Mahamadou.

Lassana is Ferguson's top choice and contact has already been made with the player's representatives.

If a deal cannot be struck, Ferguson will turn to Mahamadou, who the United manager has been following since his days with Olympique Lyon.
