It will come as little surprise to Arsenal fans that Alex Song's stay at Barcelona may only be brief. The midfielder has made just six starts for the club in La Liga this season and is yet to feature at all so far in 2013.
Arsenal fans have seen their stars leave to Barcelona with varying degrees of success, and so far Song looks more Hleb than Henry.
It has led to speculation the Cameroonian international may be allowed to leave the Nou Camp in the summer if the right offer comes in, and PSG are already said to have approached Barcelona over a transfer at the end of the season.
A return to the Premier League has to remain a possibility if the right offer comes in, and this is where Manchester United should come into the equation.
United's midfield looked good against Liverpool for much of the game yesterday at Old Trafford, but their limitations are well known, with Scholes needing to be replaced along with Giggs, who also qualifies as a central midfielder these days.
Against better quality opposition United have previously been found short, and only complacency would lead fans or management to believe they have enough.
United have been linked with a number of various midfielders over the past week, Real Betis' Benat, Everton's Marouane Fellaini, but Alex Song has something to offer too.
Among his strengths are his tackling, and his ability to play a pass, also developing an eye for goal in his past two seasons at Arsenal. His versatility and ability to fill in at centre-back has also proved a key asset over the years, just like Michael Carrick at United.
Yet the reason United should most look to secure his signature is his proven ability to link up with Robin van Persie. Now United certainly have no problems with their 21-goal Dutchman so far, but anything they can do to enhance his superb form even further has to be taken into consideration.
Song provided 11 assists for Arsenal last season, five of which were converted by Robin van Persie. The striker's memorable stunning volleys against Everton and Liverpool were both from inch-perfect passes clipped in by Song.
A deal will likely come down to price, and if PSG are bidding then United will likely find themselves unable to compete, with regard to transfer fee or wages, but they can also offer Song something the French club can't, and that's the chance to play again with Van Persie.
