The 20-year old midfielder is back in action after a 17-month layoff because of injury but has already produced some impressive displays with appearances against QPR, Schalke and Manchester United (where he received two yellow cards).
Wilshere, who has been called up to the England squad for tomorrow night's friendly with Sweden, admits he did not think he would be back to the standard he has produced so far and is looking forward to getting back to his absolute best.
"I'm quite surprised actually," he told Arsenal Player. "When I first played in the [under-21s], I was really rusty and I think it was clear for everyone to see. Everyone was just being nice to me saying 'you played well'.
"Now I'm feeling better and better as every game goes on and there's no hiding place when you're playing at the Emirates, at Old Trafford and you're in front of everyone. You have to be at a certain standard so you don't let your team-mates and your fans down.
"Mentally it has been tough because you question yourself all the time. You go to the Emirates, you watch games and you think 'Has it got quicker? I don't remember it being this quick. Can I get back to this level that I was at before?'
"But I feel good now and hopefully, with a few more games, I can get back to my best."
