Manchester United boss David Moyes is interested in Barcelona midfielder Alex Song.
Sport says United are showing interest in Song, where Moyes can guarantee him a regular start in his midfield.
However, a return to Arsenal this summer has also been mooted, where Song's agent Darren Dein has been building bridges with the club's hierarchy in recent months.
The Cameroon international has found himself a bit-part player at Barca since his arrival over 18 months ago from the Gunners.
