The Arsenal and England midfielder has not featured all season after aggravating an ankle injury in a pre-season game against New York Red Bulls back in July.

But both the player and Arsenal boss Wenger had been optimistic that he would return to play some part in the end-of-season run-in.

But speaking after Arsenal's surprise 2-1 loss at home to Wigan in the Premier League on Monday night, Wenger said: "Jack Wilshere will not play again this season and will not go to the Euros, that is for sure.

"He is not ready to practice today or next week. He makes progress, but slow progress.

"What is for sure is he will not be ready for the end of the season and not for the Euros.

"He is devastated, and you can understand that."

It was hoped that Wilshere could play some part in Arsenal's last three Premier League outings against Stoke, Norwich and West Brom as preparation for possible involvement with the England squad in Poland and Ukraine.

However, Wenger has always been clear that he would not allow the 20-year-old to report for international duty if he felt it would aggravate the problem.

"What kept him going until now was that he still felt if it was not with us, he will still have a good chance to go to the Euro, but that is over now as well," Wenger continued.

"We had a chat about it this week. His progress is not quick enough just to hope to go to the Euro."

Wenger also dismissed the prospect of Wilshere playing some part for Great Britain in the Olympic football tournament, which starts seven weeks later than the Euros but would encroach on the start of next season.

"The Olympics would be the worst idea for him," the Frenchman said.

"When a guy has not played for a year, he needs a good preparation and a slow preparation after to start the season.

"Once he is fit, he can think about the national team as well.

"It is not I do not want him to go to the Olympics, it is just that now he has other priorities than that."

Asked whether the Football Association, who are still searching for a permanent successor to Fabio Capello, had been informed of Wilshere's situation, Wenger said: "The FA know.

"At the moment, the manager is invisible, so I cannot tell him."
