He was given the job on a permanent basis after the club considered other managerial options in the summer and concluded he had earned the chance. On the pitch, the hierarchy felt his style of play allowed the forward players more freedom. United won 12 of their last 17 matches of the season.
It is understood the club's leadership team were clear with Carrick that results and performances needed to improve. On two occasions, it is understood, he was told that a recommendation would be made on his future at the club.
A day after one of those conversations, it is believed Wilcox held a similar discussion with Carrick. What is not clear is whether Carrick and his representatives knew that the recommendation was to relieve him of his duties.
Reports of his imminent dismissal became widespread, followed by information about who would replace him. At a club the size of United, keeping such developments completely private is extremely difficult. There is a feeling that officials were as transparent with Carrick as they could be.
The 45-year-old signed a two-year deal, though it is understood United contractually protected themselves in the event of an early termination.
Officials felt he brought calm and protected his players at every opportunity, a contrast with at least the closing stages of Amorim's tenure. They also liked his positive messaging to the players and the media.
