Chelsea FC has made the announcement today that Three will be the official shirt sponsor for the club starting from the 2020/21 season for three years. This will bring an end to the 5-year Yokohama sponsorship. However, they will continue to remain as the club’s Tyre sponsor. The deal is rumoured to be similar in value to Yokohama’s £40m-a-year deal.
