On-loan Barcelona midfielder Alex Song could join West Ham United permanently, according to Marca.

The Cameroonian has been a revelation at the base of the Hammers midfield since joining on loan from the Spanish giants in the summer.

A key figure in West Ham's success this term, the 27-year-old has expressed his desire to leave the Camp Nou for good when his loan stay comes to an end and Sam Allardyce is keen to land the enforcer full time.

Song has made 15 appearances in all competitions for the Hammers and recently retired from international duty with Cameroon after seemingly being called up for the African Cup of Nations.

The former Arsenal midfielder is understood to be interested Manchester United too.
