Jack Wilshere has announced he will leave Arsenal when his contract expires in July after being informed he does not feature in Unai Emery's plans.
The 26-year-old has spent 17 years on the books of the north Londoners, making his debut aged 16 as he became the club's youngest-ever player.
Wilshere has since gone on to make 197 appearances for the Gunners, winning two FA Cups, but has had to constantly battle injuries since breaking into the first-team.
The England midfielder had been offered a new deal to remain at the Emirates Stadium but on reduced terms due to his injury history.
Having not signed the extension in the hope of Arsenal improving their offer, Wilshere met with Arsene Wenger's successor Emery last week to discuss his future.
The Spanish coach informed Wilshere he could offer him no guarantees over his playing time and, as a result, the central midfielder has taken the decision to leave when his deal runs out next month.
On Instagram, Wilshere said: "Following a number of extensive conversations with those at the club, and in particular a recent meeting with the new manager Unai Emery, I felt that I was ultimately left with little choice but to make the decision that I have due to purely footballing reasons.
"As has widely been reported I, along with my representative, have been in talks with the club for a number of months with the view to signing a new contract to extend my stay at the Emirates.
"My intention throughout these discussions has always been to remain an Arsenal player. I have been on the books at Arsenal for 17 years and have always felt part of the fabric of the club. Such was my desire to stay that I had in fact recently agreed to sign a financially reduced contract in order to commit my future to the club.
"However, following my meeting with the new manager, I was made aware that although the reduced contract offer remained, it was made clear to me that my playing time would be significantly reduced should I decide to stay.
"I am sure everyone can understand that, at this point in my life and career, I need to be playing regular first-team football and following my meeting with Mr Emery I came away with the feeling that it would be very difficult for me to do so at Arsenal."
Wilshere's departure is just one of a number of major changes the club has undergone this summer as they move on from the Wenger era.
Arsenal are 28/1 to win the Premier League title in Emery's first season in charge, while they are 2/1 to finish in the top four.
