The former Chelsea and England defender joined Villa boss Dean Smith's coaching staff in October 2018. Terry helped Smith guide Villa to Premier League promotion in 2019. "It has always been my ambition to move into football management and, providing the right opportunity presents itself, I feel ready to take up such a challenge," said the 40-year-old. Terry said it was "a difficult decision to make" and added that he wanted to be as respectful of the manager and all Aston Villa employees as possible. After taking my future seriously over the summer I don't believe it fair to enter a new season before being certain that I will see it through. "My immediate goals are to spend quality family time and to then hopefully be able to accept invitations from clubs and managers throughout Europe to help me achieve my objective of becoming a manager. " Terry was involved in the filling of vacant positions at Celtic in February, Bournemouth. Following promotion to the Premier League, Villa reached the Carabao Cup final in 2019-20 and, after surviving on the final day of their first season back in the top flight, finished 11th last term. Smith said: "I'm disappointed to lose John as part of my coaching staff but fully understand and respect his decision. "John has played a huge role in the success the club has enjoyed over the past few years and has been very supportive of me throughout that period. "I have no doubt that Mr. Smith will continue to be an outstanding manager. I wish him the best in the future."
