Clifford was previously owner and chairman at Ilkeston, but expressed a desire to return to the touchline.
He now becomes part of Steve Chettle’s backroom staff.
“It feels really good to be back,” he said prior to overseeing his first training session on Thursday. “It was nice walking through the gates again and, although it’s been a few years, it felt like I’ve never been away.
“I just wanted to get back on the grass – I’ve missed it,” he added, when asked his decision behind the switch. “I’m a football person and definitely not a boardroom person – my day in, day out needs to be on that pitch with players and help Basford win games.”
Clifford began his touchline career at Basford in 2015 as Under 21s manager before stepping into the role as assistant to Martin Carruthers, and currently holds a UEFA A licence.
Basford Chairman Chris Munroe added: “I am absolutely delighted to welcome ‘Cliffy’ back to Basford.
“Joanne and I have massive admiration for him as a person, head coach and his wonderful family.
“Our club objective remains very focused on promotion – either this season or next – and Mark, along with all our first team and academy coaches, will provide massive support to Steve in getting us to our final goals.”
