Thierry Henry will not coach Arsenal's under-18 side having opted to continue in his role as a television pundit.
The former Gunners striker, 38, had worked with Arsenal's academy players last season during his course to gain his UEFA A Licence.
Henry, who works on Sky's Premier League coverage and also appeared on the BBC's Euro 2016 output, was offered a role within the Arsenal set-up by manager Arsene Wenger -- but was told he would have to step down as a pundit.
In a series of tweets, Henry said he accepted Wenger's decision to make him choose between jobs.
"I would like to thank [academy head] Andries Jonker for offering me the chance to coach the U18's @arsenal, which I was honoured to accept," he wrote.
"However I respect Arsene Wenger's decision and I want to wish their manager Kwame Ampadu, the boys and everyone at the club all the best for the forthcoming season."
A club source confirmed to ESPN FC earlier on Tuesday that Henry had turned down the coaching job because of the schism over his punditry role.
Wenger has a history of aiding his former players, with Steve Bould currently his assistant and Freddie Ljungberg working within the youth ranks.
Mikel Arteta, who retired at the end of last season, has taken a role working under Pep Guardiola as part of Manchester City's coaching staff.
Henry is one of the top earners at Sky -- in a job that reportedly pays him £4 million a year -- since signing for the network in December, with former Arsenal captain Tony Adams now reported to be set to return on a permanent basis.
The ex-Portsmouth and Wycombe boss, 49, underwent heart surgery last year and has already been working with Arsenal's U18s in recent weeks.
The decision by Wenger, who only has one year left on his contract, comes despite him often working as a TV pundit with beIN Sports during international breaks and tournaments, including Euro 2016.
However, those duties do not interfere with Arsenal's season, the way Henry's would have.
