For the fourth year running, Chelsea are set to start the season without a sponsor on the front of their shirts.The Blues have struggled to find a main sponsor since their deal with mobile network Three expired at the end of the 2022/23 campaign.Chelsea have gone through pre-season without a front-of-shirt sponsorGettyAnd while they’ve ultimately managed to secure a deal partway through each of the last four seasons, their new kits for 2026/27 look distinctly blank as things stand ahead of their upcoming curtain-raiser away to local rivals Fulham.Why do Chelsea not have a front-of-shirt-sponsor?As it so often does in football, it ultimately comes down to money.According to The Sponsor, who have published their annual Premier League Fair Market Value (FMV) Index, Chelsea’s sponsorship value is worth £33.6m – down £16.7m on last year, in no small part due to their lack of European football in 2026/27.However, The Telegraph report, the Blues believe the value remains around £50m.It seems, then, that Chelsea have thus far been unable to find a sponsor willing to meet their valuation.The Blues eventually struck a deal with artificial intelligence platform IFS.ai to be their front-of-shirt sponsor in 2025/26, but that deal only ran until the end of last term.Chelsea have released three new outfield shirts for 2026/27, including a third shirt featuring the club’s old badge.But all three strips have a retro feel to them at the moment given the lack of main sponsor – a situation that might please fans from an aesthetic point of view but is less than ideal for the Blues on a financial level.Chelsea were sponsored by Emirates during their maiden Premier League title-winning season of 2004/05GettyWho else has sponsored Chelsea in the Premier League?Chelsea have had 10 different front-of-shirt sponsors since the start of the Premier League era in 1992.The first of those was Commodore, whose Amiga range of computers saw its name emblazoned on the Blues’ shirts in the 1993/94 campaign.Chelsea were then sponsored by Coors beer, windscreen repair company Autoglass and airline Emirates.Technology giant Samsung and Yokohama Tyres followed before Three.Since the end of the Three deal, the Blues’ main sponsors have been sports data technology company Infinite Athlete, Dubai-based luxury housing developer DAMAC, and IFS.ai.Who makes Chelsea’s kit?Chelsea’s official kit manufacturer is currently Nike.The American sportswear giant have supplied the Blues since 2017.Chelsea’s previous kit manufacturers in the Premier League era were Adidas and Umbro.Their kit will still feature the gold Club World Cup emblem following their win last summer.
