The 20-year-old forward was preparing for Arsenal’s pre-season friendly against New York Red Bulls on Saturday when the former Southampton man got his hands on the No10 shirt.
Oxlade-Chamberlain, who moved to the Gunners from Southampton in 2011, currently wears the number 15 shirts for the north London side.
However, if The Ox has his way, Wilshere could soon be demoted as the forward took to his Twitter to warn the England midfielder that his shirt number is under threat.
