Warren Joyce will not return to the Manchester United academy, the Manchester Evening News reports.
The former U23 coach left the club in November to manage Wigan but was sacked after just 24 games, with academy director Nicky Butt put in temporary charge.
Joyce oversaw a string of reserve titles during his time with the club and brought through players such as Marcus Rashford, Paul Pogba and Jesse Lingard to the senior side.
United’s four-month search for Joyce’s replacement has made progress with some candidates being interviewed for the job.
However, Butt said in January that the Reds won’t be rushed and want to make certain they get the right.
“It’s something we’re looking at and something we’ve got to get right,” he said.
“It’s a very important age group to manage and look after. It’s the last step into the first team or into different clubs to try to make a career.
“It’s important and we’re going through the process of having interviews. We don’t want to make it a rush job and get the wrong person in.”
