He brings with him his assistant manager, Warren Feeney, while a technical director will follow shortly.

Kewell immediately also signed Crawley Town midfielder Rob Milsom on loan to his new side.

County owner and chairman Alan Hardy said: “Having now worked in football for a significant period of time, I have had the opportunity to learn from other clubs what good looks like.

“I have therefore decided to appoint a technical director, who will set the club’s overall footballing philosophy and be on hand to support and mentor the manager as required.

“Harry will, however, be solely responsible for our first-team squad, having the final say on transfers, tactics and team selection.

“He has enjoyed an excellent start to his managerial career and I am hugely impressed with his knowledge and attention to detail.

“I thoroughly enjoyed our discussions about the role and have been left with no doubt that he has a fierce ambition to succeed and a real enthusiasm to work for Notts County.

“I’m excited to see how he implements his exciting methods and look forward to him working with our new technical director.”

As part of the restructure, Darren Fletcher will be standing down from his role as vice-chairman.

“Darren and I have come to a very amicable agreement that it would be best to part ways,” explained the chairman.

“He will remain a close personal friend of mine and I thank him for the tireless effort and support he gave to me.”

Mark Crossley and academy manager Jon Goodman will take charge of the first team against Forest Green Rovers tomorrow, with Steve Chettle attending a family wedding.

Kewell’s first game in the dugout will come away at Grimsby Town in the Checkatrade Trophy next Tuesday.
