Carrick, 33, joined United from Tottenham Hotspur in 2006, and has now made almost 400 appearances for the Red Devils in almost nine years at Old Trafford.
Having signed a new one-year contract extension to keep him at United until 2016 in May, Carrick looks set to be a key player under Louis van Gaal, especially given that United have lost the last two games, in which Carrick has been out through injury.
Now, the Manchester Evening News report that van Gaal has now realised that his United side are too reliant on Carrick, and a new defensive midfielder needs to be brought in during the summer transfer window.
Daley Blind has struggled in that role of late, whilst Ander Herrera is better used further forward where he can impact the game in the final third of the pitch.
With Carrick entering the final years of his career, a younger midfielder with a more reliable injury history is needed at Old Trafford, and van Gaal now seems ready to splash the cash in order to find one this summer.
The likes of Ilkay Gundogan (Borussia Dortmund) and Kevin Strootman (Roma) will no doubt be touted as potential new signings this summer, whilst AC Milan's Nigel de Jong would offer a more experienced solution, with his contract at the San Siro expiring this summer.
