The Red Devils are third in the Premier League table, eight points ahead of sixth-placed Brighton & Hove Albion with a game in hand as they push towards the Champions League spots.
A win over Brentford at Old Trafford on Monday night would all but secure Champions League football for next term and could land interim boss Michael Carrick the permanent role.
However, Carrick's side will take to the pitch against Brentford wearing a special edition shirt with (RED) as the front-of-shirt sponsor instead of their usual Snapdragon, who have sponsored the club's shirts since 2024.
(RED) raises money to fight for health causes, including the fight against AIDS and has raised over £590M so far for the global fund and helped more than 350M people.
Tijmen Zonderwijk, co-founder at MatchWornShirt spoke on the sponsorship which should help even more funds for the cause.
"These shirts represent the very best of football - moments on the pitch transformed into meaningful impact off it. By bringing fans closer to the game they love, we’re turning that passion into something bigger, helping to raise critical funds and awareness for life-saving global health programmes around the world."
Kate Charles, Managing Director of (RED), said: "This collection shows how purpose-driven partnerships can turn the power of sport into real-world impact. Each shirt tells a story from the pitch, while also helping to fund life-saving global health programs in communities where they are needed most."
The 20-time English champions picked up a huge three points away to Chelsea last time out and must beat Brentford if they are to shurg off Liverpool who are slowly catching them in the table.
