Wilshere, 20, is set for another run-out next week against Reading, but Wenger continues to stress it must be a cautious rehabilitation for the 20-year-old.
"Jack needs a few games, progressive build-up to get his body used again to competition, to shocks, to fights, but he is doing extremely well, the situation looks very good," said Wenger, whose side will look to get their Barclays Premier League campaign back on track at West Ham on Saturday following defeat by leaders Chelsea.
"We have to be cautious, not crazy, because of his talent you are always pushed in a situation where you would like to rush him back, and we have to resist that.
"The next match should be next week and he is working very hard.
"The body is like that, when you have been out of competition for 14 months it takes a long time to find your sharpness back. You cannot rush it."
