Head coach Dean Ryan said: "I am disappointed to lose a player of Phil's distinction, leadership qualities and undoubted skill. He has been a talisman for Gloucester Rugby for 10 years and his experience was fundamental in our progress.

"He has attained the highest levels possible in the game - has captained his country and won the World Cup - and reluctantly we have to accept his decision.

"The key thing now is to ensure the continued support and development of our young but exceptionally gifted squad for the long-term."

Phil Vickery said: “The hardest decision of my life was to leave home at 19 and without a career in front of me. I was lucky enough to find that Gloucester became my home and the decision to leave the club now after 11 years is the second hardest of my life.

“Gloucester is a place that eats, breaths and sleeps rugby and when you are a player in that environment it inspires you. I have given everything I possibly can for the club, I am proud of my contribution to Gloucester’s history, and believe their band of young players is highly exciting for the future.

“Several of my close friends, who I have grown up with and played with throughout my career have moved on and that also had an impact on my decision.

“I want to be happy and I want my family to be happy. Money has never been an issue for me in playing the game I love – the motivation to play has to come from within – but to maintain that level of hunger it is time to assess my options.

“Gloucester Rugby has, and always will, remain a very special part of my life and career."
