The 35-year-old explained that he could not see himself playing for another club, per BBC World Service's Sportshour: "I probably would say so, yes. I think so. I couldn't say definitely [that I would retire] but pretty much. I just can't picture myself playing for anyone else—certainly any other club in England."
Carrick joined United in 2006 from Tottenham Hotspur and has since won five Premier League titles, two League Cups, an FA Cup, a FIFA World Club Cup and the 2008 UEFA Champions League.
It was announced on Thursday that he has been awarded a testimonial by United to be played in the summer:
Carrick remains a crucial part of United's first team, and there have been reports that he will be offered an extension to his current deal, per TalkSport.
Manager Jose Mourinho used him only sparingly at the start of the season, but the former West Ham United man is now a key part of the Red Devils' best midfield three, alongside Paul Pogba and Ander Herrera.
Carrick has made 22 appearances in all competitions this season, with United winning 17, drawing four and losing just once—against Hull City in the second leg of the EFL Cup semi-final—with him in the side, per WhoScored.com.
Per football writer Liam Canning, the 34-time England international is particularly important in allowing Pogba the freedom to roam and impact the game:
The veteran's control and stability at the base of the midfield have characterised his huge successes at United.
Carrick seemingly wants to finish his career at Old Trafford, and he surely has enough left in the tank to be worthy of another season-long contract at United.
