Diageo and existing sponsor Barclays are among the companies vying for one of football's biggest sponsorships. Barclays, the incumbent sponsor, has signalled that it may bid despite widespread expectations that it would withdraw when its existing deal expires at the end of next season. Samsung, the Korean consumer electronics giant and sponsor of Chelsea, is understood to have expressed an interest in bidding for the title sponsorship. Ford and Mastercard have also been touted as potential candidates.
