The 31 year old has suffered with injuries over the past few years
Manchester United have confirmed Phil Jones will leave Old Trafford when his contract expires this summer.
The defender has made 229 appearances since joining from Blackburn in 2011, but has barely played in the past few years due to injury.
He was part of the side which won the 2013 Premier League title in Sir Alex Ferguson's final season in charge.
In an open letter on Twitter, Jones commented: "It's always tough to leave a club. I did so already with Blackburn Rovers, all those years ago aged only 19, but I could never imagine what was to follow.
"My time at United has been nothing short of incredible.
"It's not a time to be sad. It's a time to look back, for me and my family, and be happy that I managed to live a dream at United.
"I can always say to my family and friends that not many people get to play for this club, to always be in its history and to be able to look back with such happy memories.
"I wish Erik [ten Hag] and his staff, and all the players, the best of luck for the future. He's building something here and I'll be watching, supporting, and hoping, more than anyone, that he can continue the progress we can all see already.
"I want to say thank you to everyone who has helped me at Manchester United, where I've made friends for life.
"But, most of all, my family, who stuck by me through everything.
"The biggest one to my wife and two beautiful girls. I cannot put into words the support you've given me. We've stuck together and I can't wait to see what the future holds," he added.
