With Alexandre Lacazette and Pierrer-Emerick Aubameyang to call upon Welbeck does not feature prominently in the plans of Arsenal boss Unai Emery, who is prepared to sanction and exit for the former Manchester United man ahead of the transfer window closing.
It could be a case of Turkish delight for the England international, with Galatasaray keen on securing the striker's services.
According to the aforementioned source, Galatasaray are prepared to make a significant financial commitment to bring in the pacey forward, who is believed to be open to the prospect of a new challenge.
Welbeck is yet to play a single minute of Arsenal's two games of the season so far and started just 12 Premier League games last season.
