Manchester United are attempting to accelerate the signing of Empoli defender Alberto Massacci.

Empoli have not complained but United have asked the FA to seek international clearance from FIFA for Massacci as none has been forthcoming from the Italian FA.

The FIFA spokesman added: "Our services were contacted by the Football Association on behalf of its member club, Manchester United, with regard to the international clearance for the player Alberto Massacci, since the FA was not able to receive the pertinent international transfer certificate from the Italian Football Federation."
