Southampton have been offered the chance to sign USA and New York Red Bulls centre-back Aaron Long, Sky Sports News understands.

West Ham wanted to sign Long last summer but he could not get a work permit in order for the defender to complete the switch to the Premier League.

Long now qualifies for a work permit because he has been playing regularly for USA and scored in the 4-1 victory over Canada on Saturday.

Marseille are also interested in signing Long in January, and he is believed to have a $6m release clause in his contract.
