Carson was also at Liverpool when the Reds won the Champions League, FA Cup and Super Cup, while he made more than 100 appearances for Derby County and West Brom.
But it was at City where he enjoyed glittering success, including the Treble of Premier League, FA Cup and Champions League in 2023, after spending two seasons initially on loan from Derby in 2019.
Carson became a cult hero among fans, having played only 117 minutes in total as third-choice keeper behind Ederson and Stefan Ortega for much of his time at the club.
His last competitive appearance was as a late substitute in a Champions League last-16 second-leg draw with Sporting in March 2022.
Manchester City defender Manuel Akanji, currently on loan at Inter Milan, called Carson an “absolute legend” in response to his announcement, while “The Goat” was how former team-mate Fernandinho reacted.
Norwegian striker Erling Haaland was among the other City players – past and present – to comment, writing: “Miss you pal, all the best.”
Derby, where Carson spent six years, posted on Instagram: “Wishing all the best to Scott Carson. Congratulations on a magnificent career, Scott.”
