Gloucestershire have announced that head coach Mark Alleyne has left the club after 22 years.

Alleyne joined Gloucestershire in 1986 and was the county's most successful captain of all time, winning eight one-day trophies between 1997 and 2005.

The 38-year-old was not expected to depart until September when his contract came to an end.

Chairman John Light said: "We feel it is time for change and time to move towards a new Director of Cricket."

"I would like publicly to thank Mark Alleyne for his massive contribution which has been greatly appreciated by everyone associated with the club."

Every single ball will stay with me forever Mark Alleyne

Alleyne became player-coach in 2004 and took on the role of head coach the following season when he retired from competitive cricket.

On announcing his departure Alleyne said: "I reminisce with absolute pride about the last 22 years of my life.

"Every single ball will stay with me forever and I would like to thank Gloucestershire for allowing me that wonderful opportunity.

"The time was made special by the tremendous support I received from the members and supporters alike."
