A report in the Telegraph suggests the 26-year-old wants a move back to the Premier League, and has named Manchester United, Tottenham and Everton as interested clubs.
The report also says that Liverpool were interested in the midfielder last season, and that the Cameroonian can leave for around £8million should a club want his services on a permanent basis.
With regard to Tottenham’s pursuit of the ex-Gunner, Southampton’s Morgan Schneiderlin is supposedly still their number one midfield target, but failure to land him will result in an approach for Song.
Having only made 39 appearances in two seasons at the Nou Camp, Song is considered surplus to requirements under new manager Luis Enrique, who has also disposed of other former Arsenal man Cesc Fabregas this summer.
Fabregas leads a long list of names who have departed the Catalans this transfer window, with Victor Valdes, Alexis Sanchez, Bojan Krkic, and Carlos Puyol all having left.
A solid holding midfielder, who is also comfortable in possession of the ball, Song would suit many a top Premier League team. Manchester United is an unlikely destination considering their midfield is in need of more attacking players as opposed to defensive ball-winners, and any talks with Spurs would provoke a negative reaction from Arsenal fans.
On paper, his best move could be a move back to Arsenal. Free for at least one season, and more of the holding nature, he could prove a quality recruitment at the Emirates.
