The 40-year-old has been out of work since June having stepped down after leading the Tractor Boys to the Premier League for a second time.
The Northern Irishman was a scout at Old Trafford and later an assistant manager, spending three years on the shoulders of Jose Mourinho, Ole Gunnar Solskjaer, Ralf Rangnick and even Carrick.
His former colleague has been given time to turn the current situation at Man United around, but the next three games could well spell the end of his tenure.
With games against Tottenham and Liverpool approaching in the Premier League, the task is not getting any easier for the Frenchman.
"I think McKenna could be the favourite to take over at Palace," King told Football Insider. "They've even mentioned his name at Man United.
"He was there quite some time. The problem is, is that there are too many cooks at Man United."
"There's certainly one at Crystal Palace, so again, 'do I run the football side of it or do you?'"
McKenna appointment would be a risk
There is no doubt over McKenna's ability to build up a club and a team, considering the job he did at Ipswich.
When the Northern Irishman took over, the Tractor Boys were struggling in League One and would continue to do so for another year before achieving promotion to the Championship.
Man United would be a whole different kettle of fish for the 40-year-old, but it could well be a risk worth taking.
