Jones refers to reports emanating from Spain, which claim the former Gunners star would be open to a return to his previous employers—although Manchester United are also said to be keen:
The former Premier League star has grown frustrated at the lack of opportunity at the Nou Camp.
Manchester United are also said to be keen to snap up the defender during the winter transfer window but are having to wait to see if Barca are willing to risk letting him leave.
Since his £15 million departure just over a year ago, Song has struggled to establish himself among Barcelona's heavily clustered midfield. He's started three of eight games in La Liga this season—having featured in 20 last year—and remains firmly behind Sergio Busquets in the pecking order.
While Arsenal have recently added Mathieu Flamini, their squad has very little in the way of orthodox defensive midfielders.
Jack Wilshere, Mikel Arteta and Aaron Ramsey are all far better with the ball than without it and have flourished alongside Flamini's industry and positional nous.
After his fine return, few fans would see the logic in bringing in another defensive midfielder to start, but there is certainly sense in keeping tabs on Song's availability.
Flamini has only started 29 league games in the past three seasons, missing most of the 2011/12 season with a cruciate injury. Given the impact his arrival has already had, Arsenal would be wise to provide him support.
Was my failed transfer to Arsenal difficult to swallow? At first, yes.
But you have to quickly get focused again, because if you go on thinking about it you have a grudge against a lot of people and that is useless.
I quickly forget about it and go back to work. [...]
The only person who can explain what happened is Joe Kinnear. If he is honest, he will tell it. Otherwise it will not get out of my mouth.
This link to Arsenal was always a strange one, particularly as Arsene Wenger has no shortage of similar players to Cabaye. There were several deficiencies to fill, none of which the Frenchman resolved.
Ramsey, Wilshere and Arteta are all excellent with the ball at their feet but were desperate for a more defence-minded presence alongside them, as Flamini has brought.
Song is the more likely target to be considered in January, although given Flamini's instant impact, Arsenal still have more pressing concerns in attack and defence.
