Following Arsenal's 2-1 defeat to Wigan on Monday night, the Gunners boss declares that the long-injured midfielder will be unavailable for England in Poland and Ukraine
The 20-year-old playmaker, who has not made an appearance for the Gunners this season, suffered a reoccurence of an ankle injury in January and will not recover in time to represent the Three Lions in this summer's tournament.
"Jack Wilshere will not play again this season and will not go to the Euros, that's for sure," the Frenchman told reporters following his side's disappointing 2-1 defeat to Premier League strugglers Wigan on Monday.
"He is devastated. But you can understand, because what kept him going until now is that he still felt that he'd have a chance to go to the Euros."
In wake of the news, Wilshere refused to be downhearted and wished his team-mates the best of luck on Twitter.
"My ankle is good, I just have a few niggles and having been out so long I will not be fit enough for the Euro's," he said.
"Gutted, sad, devastated..its been a test mentally for me this season and it will continue to be tough until I am back out on the pitch.
"The hardest thing is being away from the game that I love and not being to able to help my team mates get 3rd place! I will be in all summer.
"Trying to get fit so I can help the team next season! No holidays, I just want to play and show AFC fans what I can do!

"Thanks for all your support! Means a lot!"
Wenger also insisted that he would not be content if the youngster was rushed back into action to represent Team GB in the closely-following London Olympic Games.
"The Olympics would be the worst idea for him," the manager added.
"It's just because 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's fit, he can think about the national team as well.
"At the moment, it's not that I do not want him to go to the Olympics, but I think at the moment he has other priorities."
