The midfielder confirmed it will be his last season at Old Trafford and revealed the logical transition to Jose Mourinho's coaching staff in the off-season.
Unite manager Jose Mourinho has said he would be keen to add Carrick to his first-team coaching staff and the former England worldwide admits there is a good chance he could be on the bench from next season.
Carrick said: "There comes a time when as much as you don't like it, it's time to stop playing football. It's something that you have got to accept".
The 36-year-old was handed the captain's armband last summer after the exit of Wayne Rooney but has only made three starts in all competitions this season.
"So that's pretty much where I'm at, which is fine".
Sherman on decision to join 49ers: 'I'm vengeful in that way'
Consider this claim from Sherman: "It gives me the ability to control my destiny". I helped the organisation get to a great place and stay there.
As such, he's likely to take on a coaching role from next season - discussions are ongoing but "it's been kind of sorted out".
The thirty-six year old has barely featured for the Red Devils this season, making just four appearances while he had a minor operation to treat an irregular heartbeat in October.
A graduate of West Ham's youth academy alongside the likes of Frank Lampard, Joe Cole and Rio Ferdinand, Carrick went on to win five Premier League titles under Alex Ferguson. Hopefully I can get some game time and I am still enjoying training.
"I wanted to finish on my own terms so I was determined to get back fit".
Carrick has played 463 times for United with 24 goals.
