BBC journalist David Ornstein has revealed that the Gunners are in talks over what would be their first major sale of the summer transfer window so far.
After the failure to finish in the top four of the Premier League last season before the embarrassing loss to Chelsea in the Europa League final, many would have expected Arsenal to ditch several players this summer.
With only a month left before the season starts, no first-team player has been sold yet but that could change with Shkrodan Mustafi now being considered for an exit.
According to David Ornstein, the Gunners are in talks with several clubs over the possibility of selling the 27-year-old, who moved to the Emirates stadium only three years ago.
The BBC journalist also claims that apart from the potential deal to sell Mustafi, Arsenal have an eye on a move to bring in a new defender to bolster the squad.
