The Tyneside-born Carrick, 36, was diagnosed with a heart problem earlier this year and has spent limited time on the field.

He still hopes to play at some point this season to go out on his “own terms,” but knows he’s reached the end.
“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. That’s pretty much where I’m at, which is fine. It’s something you have to accept. That’s where I’m at.”
Carrick was 25 when he joined United from Spurs, and has an incredible resume to show for it. He’s claimed five Premier League titles, a Champions League crown, a Europa League triumph, three League Cups, and an FA Cup.
He’s expected to join Jose Mourinho’s coaching staff after the season, though Carrick said that’s not entirely confirmed yet.
