Carrick, who was capped 34 times by England, underwent a procedure to correct an irregular heart rhythm, having initially felt unwell during the EFL Cup win over Burton Albion last September.
"It's early days, he has a long way to go to get to the other end of the scale where I am but I will try to help him as much as I can".
Mourinho has said he would be keen to add Carrick to his first-team coaching staff and the former England worldwide admits there is a good chance he could be on the bench from next season.
It has always been expected that Carrick would hang up his boots at the end of the campaign - something the veteran confirmed on Tuesday (NZT), along with his intention to take up manager Mourinho's offer to join the coaching staff.
"There comes a time, wether you like it or you don't like it, that your body tells you it is time to stop playing football".
"You don't know what you've really got until you are tested".
He added: "It's kind of been sorted out, but we're still talking about it so there is nothing to totally confirm yet".
He said: "I had a problem during the Burton game during the second half". I had the procedure the following week.
"I'm clear now, it took a bit of time to get over. I wanted to finish on my own terms so I was determined to get back fit". 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.
"Not looking past tomorrow night, but for seasons ahead now I think as a squad we need to develop, we need to be constantly in this position and expect it of ourselves and keep them standards high".
