London - Nike will take over as Chelsea's official sportswear supplier next season in what the English Premier League club says is the "largest commercial deal" in its history.
Chelsea said on Thursday that it is a "long-term agreement" with Nike. The London club didn't give any financial details.
British media reported the deal with Nike will be worth about $75 million a season to Chelsea, which said last year it had bought its way out of a sponsorship deal with Adidas to switch suppliers.
Chelsea signed a 10-year deal with Adidas in 2013 but will be ending it after just four years.
Manchester United reportedly earns £75 million (now $91.5 million) per year from its 10-year deal with Adidas.
Chelsea's standing has taken a hit following its 10th-place finish last season in a disappointing defense of its Premier League title.
That meant Chelsea didn't qualify for either of this season's European competitions.
After seven games of the Premier League season, Chelsea is in seventh place.
