Arsenal boss Arsene Wenger is delighted Jack Wilshere is fit and firing.
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.
"We have already taken points away at Liverpool and Manchester City this season, so if we win this game we will come closer to Manchester United and we'll have played nearly all the big teams away."
