United have had a disappointing season under David Moyes, with the former Everton boss failing to live up to expectations since replacing the legendary Sir Alex Ferguson last summer. The Red Devils are languishing in seventh place in the Premier League table, currently fighting for a Europa League spot rather than the title as United fans come to terms with their fall.
But most United fans are willing to give Moyes time to turn things around, particularly with the club likely to conduct a full scale overhaul of their squad this summer, with many positions needing strengthening if the club are to challenge for the title again in the near future.
One of the areas most United fans want to strengthen is central midfield, where summer signing Marouane Fellaini has struggled immensely and has failed to live up to his £27.5m price tag, whilst other players such as Tom Cleverley, Michael Carrick and Darren Fletcher have also struggled to offer the dynamism United need in the middle.
As a result, Moyes is expected to attack the problem in the summer, and a whole host of central midfielders have been linked with moves to Old Trafford at the end of the season, including former Arsenal powerhouse Song, who is currently with Barcelona in Spain.
The Cameroon international moved to the Camp Nou back in 2012 but has found it hard to break into the first team, often playing second fiddle to Sergio Busquets in the holding midfield role. His frustration at sitting on the sidelines means he is likely to move on in the summer, and United have taken the first steps to securing his signature.
It was today reported that the 26-year-old is the subject of a £12.5m bid from Moyes' men, but the likes of Liverpool, AC Milan and Atletico Madrid are also believed to be keeping tabs on the situation. By making an offer now, Moyes is clearly hoping to trump his rivals and bring Song back to England with United.
