The 49-year-old was in charge of four Championship matches for the West Yorkshire club following the dismissal of Dave Hockaday.
Redfearn was hugely successful in those four matches, leading the team to 10 points out of a possible 12 and taking them close to the playoff spots.
Milanic was appointed the Leeds head coach on a full-time basis last month, but the Slovenian has yet to win in his tenure.
Leeds have picked up just two points in the three games that the 46-year-old has been in charge of, scoring just one goal in the process.
It has now emerged that Cellino wants Redfearn to be part of Milanic’s coaching staff for the Yorkshire derby against Rotherham United at the New York Stadium on Friday.
And this is a great move.
Redfearn has shown that he can achieve success with the Leeds players. While Milanic has yet to get the best of his team, the Englishman did his caretaker-manager’s job perfectly.
Having worked at the Leeds academy for years, Redfearn will also know many of the players inside out and can also help Milanic select the youngsters who can break into the first team.
Of course, just because Redfearn got the points during his short spell as the first-team boss does not mean that he would be a success in long term, but Milanic can certainly use his input and suggestions.
Leeds are struggling to score goals at the moment, and that is one area that Redfearn can be useful. The Whites found the net in all four of the matches that the academy chief was in charge of.
In the long run, this Leeds team will be shaped by Milanic, who may have well identified the areas that need to be worked on as the season progresses. However, for now, to get back to winning ways, the Whites boss should seek the help of Redfearn.
