The England international put pen to paper on a five-and-a-half-year deal from Crystal Palace and will wear the number 15 shirt at the Etihad Stadium.
Having established a reputation as one of the finest centre-backs in the Premier League, there is much anticipation about his arrival in Manchester.
The last player to wear the No.15 for City was Eliaquim Mangala.
Sylvain Distin, another centre-back, wore the No.15 with distinction during his five-year stay at City.
Jesus Navas, a title-winner with City in 2014, wore the No.15 throughout his four seasons with City, making 183 appearances for the Blues.
And Alfie Haaland, father of Marc’s new teammate Erling, wore it back in the early 2000s following his move from Leeds United.
