Manchester United broke Premier League kit rules during their opening fixture of the season and have been forced to make an amendment.The Red Devils suffered a disappointing opening day defeat to newly promoted Hull City at the MKM Stadium last weekend.Man United will be forced to wear the Premier League badge on both sleevesGettyThe 13-time Premier League winners went into the campaign without a sleeve sponsor following the end of their contract with DXC Technology.It was a £20million pound a year deal which dates back to 2022.However, Premier League rules dictate that clubs without a sleeve sponsor should display the competition’s badge on both arms.The club and the Premier League have refused to comment on the fact that Michael Carrick‘s men left one side completely empty.Man United are expected to have the top-flight badge on both sleeves when they return to action against Ipswich at Old Trafford on Sunday.Commercial searchThe Red Devils are still seeking a new shirt sleeve sponsor, having had one for the past eight seasons.Interestingly, the DXC Technology branding made a brief appearance on the new 2026/27 home kit during the final two fixtures of the 2025/26 season.However, that marked the final outing of the partnership, as the commercial contract officially expired at the conclusion of that campaign.The club’s official 2026/27 kit launch imagery and promo photoshoots all sported completely blank left sleeves.Currently, the Old Trafford outfit have a primary front-of-shirt sponsor with mobile technology brand Snapdragon in a deal worth over £60million per year.Carrick suffered only his third defeat in 21 matches last weekendGettyAdditionally, Betway holds a major £20 million-per-season training kit sponsorship.Mauled by the TigersHowever, the sleeve sponsor error will be the least of United’s worries following their loss to the Tigers.After the final whistle, captain Bruno Fernandes said: “Every away game we give too much of the ball to them. In the first 20 minutes, the goalkeeper was the one with the most touches. “We needed to press more, be more aggressive, and then again we need to work on set plays and not concede these types of goals. Against these types of teams, they are waiting for that moment.”Carrick said: “Yeah, some [of the game] was okay, obviously bits to improve on. It was never going to be perfect today but I think going behind and giving ourselves a lot to do makes it more difficult, probably a typical one of those games of a newly promoted team at home.“You can’t give them much, they’ve got a lot to hold on to, and then after that, we had moments, we had opportunities, we just didn’t have that spark to then put the chances away or create any more.Carrick will hope his team will be more prepared ahead of another fixture against a newly promoted sideGetty“Listen, we’re bitterly disappointed with the result today but it won’t knock us.”He added: “Inside, we are hurting. The boys know we need to get better.“We’ve lost one game and it’s a bad one to lose. But it won’t change anything.”
