Former Dons coach Dave Hockaday and sports scientist Damien Doyle also make the move to the Walkers Stadium.

"Adrian has a fantastic work ethic and is a great organiser," Allen told the Foxes website.

"He is an up-and-coming coach who has shown great dedication to learn, improve and develop."

And Allen is delighted with the other two members of staff joining the club.

He added: "Dave is a good sounding board. He was first-team coach at Watford and has got the experience of getting promotion to the Premiership. I will learn from him.

"Damien's work involves prehab and rehab, speed training, individual power programmes, core ball work and body conditioning work for the players.

"Gone are the days of just managing the team and hoping for the best. We are constantly looking at new ideas to help us gain any advantage we can."
