Chelsea have confirmed that Infinite Athlete will be their front of shirt sponsor this season.
A deal for the remainder of the campaign worth over £40m has been agreed with the US-based data company, whose name will be on Chelsea shirts from Sunday.
Their women's team kick off their WSL campaign and title defence against Tottenham on Sunday evening and will have Infinite Athlete's logo on their shirts for the televised fixture.
The men's team will follow on Monday when they travel to Fulham. The brand will also appear on the sleeves of Chelsea's training kit.
