Chile played nice football, but likewise were not afraid to be overly aggressive when required.
And Wilshere feels the match was a valuable experience for England.
"South American teams like to make little fouls and break the game up, which gets frustrating," admitted Wilshere.
"We could learn a bit from them, sometimes, maybe when they're counter-attacking maybe a little foul like they did doesn't hurt.
"Once they did a little foul it slows play down, we have to start again, build up and they're all back. It makes it difficult for us.
"There are a few South American teams out there, so at least we know now what to expect from them and we'll learn from it.
"We don't want to lose two on the bounce at Wembley. We'll recover from Chile, we'll get ready, we'll watch it again and learn from it."
Wilshere insists that Chile's possession game was one of the best he had come across.
"The last time I played against a team like that was Barcelona, the way they keep the ball, the way they play out from the back and when they don't have the ball they press, they pressed high and made it difficult for us."
Wilshere insisted that he will be fit to play Germany despite picking up a knock against Chile.
Wilshere said: "I got a dead calf. Especially against South American
opposition you expect fouls like that. I'll be all right."
Pain for Jack?
The Mirror's Oliver Holt reckons Wilshere's fitness could harm his chances of making England's World Cup squad.
Arsenal midfielder Wilshere suffered a stress fracture of the ankle in 2011 and subsequently endured 14 months on the sidelines, while he also underwent minor surgery over the summer.
The 21-year-old has been affected an ankle knock this season, too, and that, coupled with the form of Aaron Ramsey and Mesut Ozil, has seen him unable to command a permanent place in the Gunners' starting line-up.
Holt told the Sunday Supplement: "I am a massive fan of Wilshere and think he has the potential to be a really important player for England, especially when he plays further forward - but I don't think he is fully fit.
"It is easy to forget how long he was out for and how bad his injury was and I think it will be a long process for him to fight his way back.
"It looks to me - though I may be totally wrong - that he is playing with a bit of pain and as he builds his way back he is going to be below what we thought.
"I hope he will get fitter and fitter and if he is fully fit he is a shoo-in for Brazil - but picking a World Cup squad is going to be down to things like that."
Roy Hodgson believes Wilshere needs a good run in the Arsenal team in order to hit top form at the World Cup.
He said: "There will be 28 games that he can possibly play before we go to Brazil so it's not something that bothers me enormously in November.
"That question could be a relevant one at the end of April or the start of May if he is still not playing games, but at the moment, I am just happy to accept that."
