Nike, Adidas and Warrior are all interested in securing a world-record deal to supply and distribute Manchester United's kit, reports BBC.
All three sportswear giants are in talks with Old Trafford officials as Manchester United bid to secure a long-term deal when their current agreement with Nike expires at the end of next season.
Manchester United are believed to be holding out for a long-term 10-year agreement worth around £600 million. Such an offer would dwarf the current record agreement in football for a kit deal - Real Madrid's £31 million-a-season deal with Adidas.
Nike have held the rights to Manchester United's kit since 2002 with the current deal worth approximately £24 million to the club. As part of that contract, Nike held a right to exclusively renegotiate the deal, but that is now believe to expired.
The Portland-based company does still have first option to match any offer that is made, leaving Adidas and Warrior with an uphill task to land the contract.
A Nike spokesperson told BBC Sport: "United is one of the greatest clubs in the world and we're continuing discussions with them."
Puma not in contention
One major company not believed to be involved in negotiations is German giant Puma, who have recently agreed a five-year deal with Arsenal worth £30 million-a-season, are not believed to be one of the main contenders to land the contract.
Puma are pushing hard to get the most out of their with Arsenal as they prepare to launch their first Gunners kit next week. Agreeing a new deal with Manchester United would not only cost the company a large amount of money but will also compromise their relationship with the north London outfit.
Decreasing market value
Manchester United's seventh place finish in the Premier League last season threatened to cost the club a lot of money. They no longer have Champions League football at the club and, without Sir Alex Ferguson, have an uncertain future as a top Premier League club.
However, the fact that sportswear giants are willing to smash the world record for a kit deal in order to seal the rights to Manchester United's kit is a massive vote of confidence for the club. Any deal will go a long way to filling to void left behind by the lack of Champions League football.
Warrior, owned by shoe giant New Balance, entered the football market for the first time in 2012 after agreeing a six-year deal worth £25 million-a-season with Liverpool. They have since gone on to secure deals with Porto and Stoke City amongst others.
However, Manchester United would be by far the biggest deal for the company so far and it remains to be seen whether they can match it with seasoned expert companies like Adidas and Nike.
