Wilshere knows it's time for the team to regain their form, and says the whole squad have a responsibility to ensure they take three points from Reading.
"We have got some great leaders in this team - people like Thomas Vermaelen and Mikel Arteta," Wilshere said. "But all the players can lead by example. We all have to step up now, it's a tough time but we have to stick together and be united.
"A lot of people are criticising the manager at the moment, but there will be a time when they look at the players and ask questions of us. We don't want that, so we have to step up and be counted.
