Diaby has not featured for The Gunners since the Capital One Cup defeat to Southampton in September last year.
Diaby is without doubt one of football’s unlucky ones.
Magnificently talented and highly rated both at home and in England the Frenchman was the natural successor to Patrick Vieira.
But, at age 19, a horror challenge from Sunderland’s now forgotten defender Dan Smith in May 2006 left him with a broken ankle and he has not been back in regular action since.
Now it would appear that Arsenal can no longer be sentimental toward the talent - who looks set to become a free agent in the summer.
However, while this was expected, Arsenal will also allow one other defensive midfielder go in the summer, according to the same report.
The emergence of Francis Coquelin in recent weeks has seen the need for either Mathieu Flamini or Mikel Arteta reduced. Arsenal are also said to be planning a big name midfield signing, so one of the two is set to depart.
Arteta is club captain, so would be the likely one to stay, however he has had an injury ravaged season. Flamini is in his second stint at the club and has not been as impressive this term. Both are free agents so it will be interesting to see which one joins Diaby out of the Arsenal exit door.
