Galatasaray have told Arsenal they must go higher for Sacha Boey.
The France U21 right-back, who has been watched regular by technical director Edu's scouts, has attracted a first offer from the Gunners.
The London Evening Standard says a £20m bid has been tabled and rejected by Gala.
However, the door hasn't been shut on Boey's sale.
Instead, if Arsenal agree to go to £21.5m then Gala will sell the youngster.
