The 36-year-old, who joined Manchester United from Tottenham Hotspur in 2006 for an £18m fee, became a mainstay in his side over the years and has a decorated trophy cabinet - winning five Premier League titles, one FA Cup and one Champions League trophy.
Carrick has been restricted to only four games this season after he was diagnosed of an irregular heart rhythm earlier in the season, a condition which he said formed a major part in his decision to retire.
"So that's pretty much where I'm at, which is fine".
Carrick grew up near Newcastle but moved to West Ham aged 15, where he made his professional debut.
The Old Trafford club captain told a news conference on Monday: "There comes a time, wether you like it or you don't like it, that your body tells you it is time to stop playing football".
While Carrick has always had his critics, he has been admired by every United coach he's worked with, from Alex Ferguson all the way through to Mourinho. It's something you've got to accept so that's where I am at.
He said: "I had a problem during the Burton game during the second half".
"It started in the Burton game and then happened again in training", Carrick added, discussing his health problem. I had the procedure the following week.
'It took a little bit of time to get over but there were some times when, for two or three days, I was thinking "am I going to carry on playing or not?" or "is it kind of worth it or not?" but that quickly passed.
"I got back fit and I wanted to finish on my own terms really".
"Not looking past tomorrow night, but for seasons ahead now I think as a squad we need to develop, we need to be constantly in this position and expect it of ourselves and keep them standards high". At least I could decide and not be forced because of that, so I was determined to get back fit.
