Nike formally announced on Thursday that it has signed a deal with Chelsea that will see the world's largest shoe and apparel company outfit the English Premier League team.
Chelsea, who had six more seasons with Adidas, confirmed the agreement, calling it the "largest commercial deal in the club's history."
Chelsea confirmed in May that they were ending a partnership with the German sportswear firm six years early at the end of June 2017. That deal was reported to be worth £30 million annually.
The length of the deal and the terms were not disclosed, although reports had tabbed it as a 15-year deal at more than £60 million a year -- a total of £900m.
"Chelsea is a world-class club with a rich tradition and passionate fans across the globe," said Nike brand president Trevor Edwards. "The partnership with Chelsea reinforces our leadership position in football. We are excited to help grow the club's global reach, serving players and supporters with Nike innovation and design."
Chelsea director Marina Granovskaia said the new deal will offer the west London club a unique opportunity in brand development.
"This is an incredibly exciting and important deal for the club," she said. "Like Chelsea, Nike is known around the world for its excellence and innovation and we look forward to working together in what is sure to be a successful partnership."
"We believe Nike will be able to support our growth into new markets as well as helping us maintain our place among the world's elite football clubs."
