And England boss Gareth Southgate has been clear that Wilshere must be playing more regularly in the Premier League if he is to receive a call-up.
Wilshere was again ignored as West Brom midfielder Jake Livermore and Burnley's uncapped Jack Cork were added to Southgate's squad for Wembley friendlies against Germany and Brazil after a spate of withdrawals.
However, Wilshere is focusing on winning a place in Arsenal's league team before worrying about getting into England's World Cup squad, having not appeared for his country since Euro 2016.
"I've said before in many interviews that I've just come back to full fitness, I'm happy at where I am playing-wise," Wilshere told Sky Sports.
"I'm trying to get into the Premier League team and fight my way into that team. So at the moment I am concentrating on the now, the future will take care of itself. All I've got to do is stay fit and play my football.
"I've got a great relationship with the boss [Wenger], I've heard the boss speak in previous press conferences. He's assured me that I will get some playing time. I want to stay at this club, I've said that many times.
"I left last year to get some football [spending the season on loan at Bournemouth]. I've done that, I'm back now, I'm fit and I'm ready to play."
Not the result we wanted. Thanks to the fans for your support. Big one in a couple of weeks. The hard work continues pic.twitter.com/cdixLUlHIm— Jack Wilshere (@JackWilshere) November 5, 2017
He added: "I want to be playing for my country. I am a proud Englishman. But it is down to the manager [Southgate]. He didn't select me. He said I need more football.
"That is what I have got to do. I have got to take it on board, try to get into the Arsenal first team and hopefully I'll be selected."
Wilshere is one of a handful of Arsenal stars whose contracts are set to expire at the end of the season, along with Alexis Sanchez and Mesut Ozil.
