Wilshere admitted he was shocked to be recalled to the starting line-up but happy Arsene Wenger told him he was playing this morning.
"The boss came up to me and said he was going to start me from the start and I was shocked, to be honest," Wilshere told BBC Sport.
"To be honest after 60 (minutes) I was cramping up. It was just literally my legs were going."
Wilshere described how changes since he was injured meant it was like playing in a different team.
"It's great to be back, especially with the new team. Last time I played it was with Fabregas and Nasri and now there's Arteta and Cazorla so it's like a new team and a new me.
"It's been very tough for me, for any player who's been injured it's tough. Luckily for me I've got my family. I've got my son now who's helped me through it.
"You question yourself every day are you going to get back to that level? You have up days and you have down days.
"The fans have been great for me, they've been so positive. Even through the darkest times they really helped me."
