Kevin MacDonald has decided to bring to an end his long association with Aston Villa Football Club.
The former double-winning Liverpool midfield player became synonymous with the success of Villa's academy and reserves.
Since his arrival at Villa in 1995, he has overseen the development of such players as Gareth Barry, Gabby Agbonlahor, Marc Albrighton, Ciaran Clark, Barry Bannan, Andreas Weimann, Craig Gardner, Gary Gardner, Darius Vassell, Steven Davis, Liam Ridgewell, Thomas Hitzlsperger, Lee Hendrie, Jlloyd Samuel and Gary Cahill, to name a few.
As manager of Villa reserves, he secured a Premier Reserve League North title in 2003-04, and four Reserve League South titles in five years from the 2007-08 season and a national play-off triumph in 2008-09.
At the beginning of the 2010-11 season he stepped into the breach as caretaker manager of Villa before assuming a first-team coaching role alongside reserve team duties last season.
Chief Executive Paul Faulkner said: "As a club, we are immensely grateful for the contribution Kevin has made in more than 17 years at Villa.
"He has been an integral part of the success we have enjoyed at academy and reserve team level and, in assuming his caretaker responsibilities at the beginning of the 2010-11 season, he cemented his position as a man who will always command respect at this club.
"The whole of Aston Villa Football Club will wish Kevin well."
Kevin said: "I've had an incredible 17 years at Aston Villa, one of the biggest clubs in the country, and wish to thank all the staff and players I have worked with during my time at the club.
"I wish Aston Villa every success in the future."
