Michael Carrick's switch from Manchester United's playing squad to the backroom team will be instant - with Saturday's FA Cup final his first coaching assignment.
Veteran midfielder Carrick hung up his boots on Sunday after playing 85 minutes of United's final Premier League game of the season against Watford.
The following day he began his new job as a member of manager Jose Mourinho's coaching staff, with the small matter of this weekend's clash with Chelsea at Wembley to prepare for.
"It changes overnight," Carrick said. "I am not training this week. I am going to jump on the staff."
The 36-year-old did have other options as he approached the end of his playing career but the chance to work under Mourinho was too good to refuse.
"A couple of years ago I thought maybe it would be a good thing to spend time with the family, but then it's about timing and opportunities," said Carrick, who made 464 appearances for United over 12 years after earlier spells with West Ham and Tottenham.
"You never know what is going to be around the corner. As soon as this came up I didn't think twice.
"He is one of the best, he's been around for many years and it all fits in. I've been at this club, and it is such a great club, so I obviously know the club and the manager.
"So learning from him and the backroom staff, and trying to bring the kids through and have an influence on that just fits. Hopefully it still fits in a couple of years' time."

Manchester United captain Michael Carrick has announced his intention to retire at the end of the season and join Jose Mourinho's coaching staff.
The 36-year-old is the longest-serving player at Old Trafford, having joined from Tottenham in 2006 and gone onto win the Champions League and five Premier League titles, among many other trophies.
Carrick, capped 34 times by England, has looked likely to leave United in recent summers only to pen extensions at a club that rewarded his fine service with a testimonial last year.
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.
It has long been expected that Carrick would hang up his boots at the end of the campaign - something the veteran confirmed on Monday, along with his intention to take up manager Mourinho's offer to join the coaching staff.
"There comes a time when as much as you like it or don't like it, your body tells you it's time to stop playing football," the 36-year-old said.
"So that's pretty much where I'm at, which is fine. It's something you've got to accept so that's where I am at.
"It's kind of been sorted out (for a coaching role). We're still talking about it, to be honest, so there's nothing to totally confirm as yet.

Manchester United midfielder Michael Carrick has signed a new one-year deal at Old Trafford, according to Paddy Crerand.
The former United defender told MUTV that veteran midfielder Carrick will stay on in Manchester following the arrival of Jose Mourinho.
Something that happened today that nobody has mentioned, and I'm delighted that he has signed another contract: Michael Carrick. He's signed a contract for another year.
There was a situation where it looked as if his contract was up at the end of this year and that was it, but from what I'm gathering he's there for another year.
Michael Carrick has set his sights on earning a place in Roy Hodgson's Euro 2016 squad.
Carrick is likely to be included in Hodgson's squad for the upcoming qualifiers against San Marino and Switzerland, which will be named on Tuesday afternoon.
After a season interrupted by injury, the Manchester United midfielder found his way back into the England squad in the Spring and impressed during the 4-0 win over Lithuania and the creditable 1-1 draw against Italy in Turin.
With Jack Wilshere out through yet another ankle injury, Carrick has a chance to stake his claim for a place in England's midfield over the next few weeks.
And after missing out on Euro 2012 and last year's World Cup, the 34-year-old is determined to make the cut for next summer's tournament in France.
Of course I would like to go. I have been involved in the squad since the World Cup. I am looking to stay involved as much as I can.
It is down to me to play enough here and play well enough to warrant a place.
Michael Carrick has signed a one-year contract extension at Manchester United.
Carrick has been one of Louis van Gaal's best players since he returned from an ankle injury he suffered last summer.
The 33-year-old's contract was due to run out in June, but the club confirmed at a press conference on Friday that the midfielder had extended his current deal by 12 months.
