'It was a pleasure to train and spend two years with you. Thanks for everything, you helped me and I wish you the best for you and your family.'
Wright's career began at Ipswich Town where he made 240 appearances from 1995-2001, before joining Arsenal for a fee of £6m.
Wright could not hold down a place in the first team, though, making just 12 appearances and he left at the end of the 2001-02 season for Everton.
Further spells at West Ham, Southampton on loan, Ipswich Town, Sheffield United and Preston North End - where he spent just one week - followed before he arrived at the Etihad.
Wright won two caps for England in friendlies against Malta in 2000 and Holland in 2001, and was a member of the Euro 2000 squad.
As Wright retires, his 17-year-old son Harry is following in his footsteps after signing a professional contract as a goalkeeper at the end of last year with Ipswich.
