Wilshere is finally back in action after 17 months sidelined following a stress fracture in an ankle.
The Emirates boss said: “Jack can cope with all the expectations because the one thing he has learned during that long spell out is that 17 months in the life of a young boy is massive.
“So I just want Jack to enjoy playing again. He is a boy who just loves to play and the most important thing is to keep that happiness on the pitch.
“Saturday is a very important game for us away to one of the big teams of the Premier League.
