"I think it's pretty much already been said, to be honest with you, there comes a time when, as much as you like or don't like it, your body tells you it's time to stop playing football", he stated. "That's where I'm at and you have got to accept it".
Youngster Scott McTominay's recent run of good form and solid performances has earned the Manchester United midfielder a first global call up for Scotland and club boss Jose Mourinho has put his rapid rise down to the young lad's humility and readiness to listen, learn and work very hard.
And he is delighted that Mourinho has given a chance to a player who, like Marcus Rashford and Jesse Lingard, has continued the long tradition of home-grown products breaking into the Manchester United first team.
Carrick, 36, has featured 463 times for the Red Devils since making a £18m switch from domestic rivals Tottenham in 2006 and has won every trophy on offer including five Premier League titles and the UEFA Champions League. "I'll try to help him as much as I can and I'll give him some advice, but credit to him, he's done great so far".
"It's kind of been sorted out (for a coaching role)". "We're still talking about it to be honest so there is nothing to totally confirm yet but it's looking likely". At least I could decide and not be forced because of that, so I was determined to get back fit.
"There were some times there, two or three days, when I wondered whether I would carry on playing or not, is it worth it or not?"
Carrick admits a heart problem that required minor surgery earlier in the season has played a part in his decision to retire but he insists he is still ready to play a part if needed in the final three months of the campaign that could yet end with FA Cup and Champions League glory.
The classy playmaker arrived at the club from Tottenham Hotspur in the summer of 2006 and was awarded a testimonial a year ago, in recognition of his magnificent service to the Reds.
In his prime, he was good enough to play for Manchester United in that deep-lying central midfield role, but he's always been one of their lesser players.
