Gary Mills has left Alfreton Town after 20 months as full time manager to take up the vacant post of manager at Tamworth who sacked Mark Cooper on Tuesday of this week.
Mills, 45, moved from the Impact Arena after an undisclosed financial settlement had been agreed between the two clubs.
Mills's assistant, Darron Gee, 44, has accepted Alfreton chairman Wayne Bradley's request to take over the reins at the Impact Arena and he is now in charge of the Reds for the foreseeable future.
Club captain Marcus Ebdon, 36, has been appointed assistant to Gee.
Alfreton chairman Wayne Bradley commented: "The deal is an amicable one and I would like it to go on record that Tamworth have been as professional as possible throughout the past couple of days.
"They (Tamworth) approached us for permission to talk to Gary which was granted and he then confirmed he wanted to return The Lamb where he has managed before.
"It is not a case of bigger clubs or anything like that, Gary simply wanted to work with a full time club - especially one that he knows - and with them training three times a week, he will get his wish of being able to be involved more on the training field.
"Gary leaves us with our sincere thanks for all he has done at Alfreton and with our best wishes for the future.
"The mood in the Reds camp is still very positive and I am certain that under Darron and Marcus we will be as ready for this Saturday's home league game against Leigh RMI as we would have been had Gary still been here.
"Hopefully Alfreton's and Tamworth's paths will cross in the future at the higher plain."
Mills said his goodbyes to the Alfreton players at Thursday night's training session.
