London (AFP) - Chelsea have signed a club record kit deal with Nike that is reported to be worth £60 million (S$101.33 million) per season to the Premier League club.

The Blues have been in talks with American sportswear giants Nike since May, when it was confirmed Chelsea were ending their partnership with adidas six years early at the end of June next year.

That deal with the German firm was said to be worth £30 million annually, but it will be dwarfed by the Nike agreement, which is understood to see the company make the full kit for Chelsea's first-team, academy sides and ladies' squad for the next 15 years.

Chelsea will earn an estimated £900 million by the time the deal, which starts from next season, expires in 2032.

Manchester United, the Premier League club with the most visible global profile, have a 10-year deal with adidas, which started last season and is worth a total of £750 million.

Spanish champions Barcelona are said to receive £120 million-a-year from their agreement with Nike.
