PUMA and Man City are linking up from next season.
The new deal, worth up to a reported £600 million over the next 10 years, is the biggest of its kind for the German sportswear company, who take over from Nike's current six-year deal worth roughly £20m a year.
Starting from July 2019, PUMA will deck out the champs as well as City Football Group (CGF) sister clubs in Australia (Melbourne City FC), Spain (Girona FC), Uruguay (Club Atlético Torque) and China (Sichuan Jiuniu FC) across men's, women's and youth teams.
PUMA teased the news with billboards across the city.
The agreement is the second largest partnership in England taking over from PUMA's current £65m-a-year deal with Arsenal, behind only Manchester United's monstrous £75m-a-year deal with adidas.
The Herzogenaurach-based sportswear brand may be losing Arsenal at the end of the season, but the addition of Manchester City adds a top tier club to their already impressive roster that includes Borussia Dortmund and AC Milan.
PUMA and Man City are set for a big 2019/20 season.
