Manchester City have agreed a new 10-year kit manufacturing deal with sportswear giants Umbro.
The agreement replaces a previous four-year arrangement with Le Coq Sportif which was reportedly worth £10million.
The value of the new deal has not been revealed.
Manchester City chief executive Garry Cook said: "We are thrilled to announce this key partnership. We are building a successful and sustainable football club for the future and our partners are integral to that."
Umbro will also be investing £100,000 in 'Manchester culture' to work alongside City and other local organisations 'to support and inspire creativity across the city'.
