He was at the heart of the youth system that brought through a host of famous home-grown players at the club in the 1990s.

And he has been heavily involved in the development of young talent at the club for most of the years since then.

A former player, he joind Carlisle in the early 1990s from Barnsley before becoming United's youth development officer.

He worked under promotion-winning managers Mick Wadsworth and Mervyn Day and later had a spell as joint manager with John Halpin and Michael Knighton.

He was part of the management team under Nigel Pearson that was at the helm when Jimmy Glass' famous goal saved Carlisle from relegation in 1999.

After spells with Newcastle United, Huddersfield Town and Gretna, he returned to Carlisle in 2005 to head their centre of excellence.

He was part of the youth set-up that led United's under-18s to the FA Youth Cup quarter-finals in 2005/6, and remained at the club from that time, most recently holding the role of head of academy coaching.
