Manchester United veteran Carrick announced he would be hanging up his boots at the end of the season during the Red Devils' pre-match press conference ahead of tonight's Champions League showdown against Sevilla.
Carrick underwent a treatment for irregular heart rhythm a year ago after he complained of feeling uneasy in Manchester United's clash against Burton in the Carabao Cup.
"There comes a time, whether you like it or you don't like it, that your body tells you it is time to stop playing football".
In January, United boss Jose Mourinho said he expected Carrick to retire at the end of 2017-18 and join the Old Trafford coaching staff - a move the player himself acknowledges as his likely next step.
"It s kind of been sorted", added Carrick. "We're still talking about it to be honest so there is nothing to totally confirm yet, but it's looking likely".
United boss Jose Mourinho suggested at the beginning of the year that the 34-cap England worldwide would likely bring the curtain down on his career at the end of the campaign and, speaking to reporters ahead of Tuesday's meeting with Sevilla, Carrick confirmed the news.
United last hosted a Champions League knockout game in 2014 and skipper Carrick says it is high time they competed again for European football's top trophy. Carrick made just one Premier League appearance this season and saw Nemanja Matic partner Ander Herrera and lately Scott Mctominay as his replacements in the United midfield. For two or three days I was thinking am going to carry on playing is it worth it but that passed and I got fit.
"I need to keep myself fit and ready".
Obviously, the news has come as an upsetting incident for United fans, but won't be too anxious about a replacement for the 36-year-old with the current emergence of youngster Scott McTominay.
'I understood after getting back fit that I wouldn't be playing as many games as perhaps I might have done, but that's something that I understood. "I've been training hard and we'll see what happens for the rest of the season", said Carrick.
