The England international has revealed that a number of his teammates put photos of one another's wives or girlfriends on display as "banter".
During an interview with ESPN, Wilshere was shown a photo of Higuain's other half Soledad Fandino, to which the midfielder replied: "That's the sort of picture that will go right up on the bulletin board in the changing room.
"Some of the lads like to put up photos of other players' wives and girlfriends and have a bit of banter. I'm not going to say but it's not the English players. There are so few of us, anyway."
Wilshere has also claimed that it would be "amazing" if Arsenal manage to sign Wayne Rooney from Manchester United.
