Relevent Football Partners and UC3 — the joint venture between UEFA and the European Club Association — are “launching an official match ball tender for UEFA’s men’s club competitions,” with the winner to “secure the rights” starting in the 2027-28 season. Sources cited by THE ATHLETIC said that there has been interest “from multiple parties in striking a deal.” Sources said that Adidas, who has held the sponsorship agreement since 2001, wishes to retain its sponsorship, but Nike and Puma have also “claimed interest.” Sources said that UC3 and Relevent are “open to bundling” the Champions League, Europa League and Conference League “or keeping them apart, depending on which deal makes the most sense” (THE ATHLETIC, 3/13).
