Carrick, who is a former England worldwide, joined the Red Devils from Tottenham in 2006 when United's retired veteran manager, Sir Alex Ferguson convinced him to swapped White Hart Lane for the Old Trafford.
The 36-year-old, who won 34 caps for England, underwent a procedure in November to treat an irregular heart rhythm, after which he declared himself "healthy", but he has only played three times since. "That's pretty much where I am at". "You can't live like you've had a career before you've had the career - you've got to earn it".
On the topic of joining Mourinho's staff he said: "It's kind of been sorted out, but we're still talking about it so there is nothing to totally confirm yet". He's only seen action a handful of times this season, but on the eve of United's hosting Sevilla with a UEFA Champions League quarterfinal berth at stake, Carrick still maintains that he'll play a role with the current team before season's end.
'Obviously, I had the problem in the Burton game, when it started during the second half, and then had a few tests after that, ' he told the media ahead of tomorrow's game. "There were two or three times when I wondered whether it was worth still playing, but I soon got over that".
'I got back fit and I wanted to finish on my own terms really.
