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 Â£10million.
The value of the new deal has not been revealed.
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 Â£100,000 in "Manchester culture" to work alongside City and other local organisations "to support and inspire creativity across the city".
