Hughton has therefore faced heavy pressure throughout the season, with reports previously suggesting he is one defeat away from the sack.
At one point, Celtic boss Neil Lennon was touted as favourite to replace the 55-year-old - but then Norwich went on to beat Tottenham and the scrutiny on Hughton's position weakened.
Now, though, Goal are reporting that Hughton expects to leave Carrow Road at the end of the season, with Lennon not the only target in mind to replace him. His position will not have been helped by another heavy defeat to Southampton.
Indeed, could Mackay be the perfect man for the job?
The Scot has proved his credentials in taking Cardiff City up to the Premier League and then enjoying a start to the season that would have been seen by most chairmen as a terrific return for a coach in his position. His only problem was that he clashed with Vincent Tan, a man intent on running things his own way.
Cardiff could not be said to be doing any better without Mackay, with the Bluebirds now in the relegation zone, something the 42-year-old managed to avoid during most of his time in Wales this season.
And an added bonus for Norwich would be the lack of any compensation were they to move for Mackay, as opposed to a candidate already in a job - namely Lennon, who Scottish champions Celtic would likely want a considerable fee for.
But perhaps the factor that will seal the deal is that Mackay spent six years at Norwich as a player and made over 200 appearances for the club. The Scot did not enjoy such a record anywhere else.
"I'd love to go back into the Premier League at some point. Absolutely," Mackay is quoted as saying recently.
"Norwich are a previous club of mine and they are in the Premier League. It's a club I know well but I'm in no rush to take people's jobs right now. Certainly not at this point in the season."
But if Hughton is relieved of his duties, that might just change for the Scot.
