Manchester United are in discussions with a number of major organisations that could see a new name appear on the front of their shirts from 2021.
The current Chevrolet deal, which started in 2014, is worth more than £450m over seven years and remains the biggest sum paid to a football club for shirt sponsorship.
Industry sources are confident a new deal will see United match or even surpass their current agreement.
Around a fortnight ago, United's executive vice-chairman Ed Woodward made clear the importance of sponsorship revenue to future investment in the playing squad.
A United spokesman said on Thursday: "Chevrolet is a fantastic partner. The sponsorship continues to achieve its objectives for both parties and we will continue to work to activate and maximise it."
The current Chevrolet deal equates to £47m per year and was more than double the previous sponsorship with AON.
AON still sponsors the United training kit and training ground - a deal which nets the club £17m a year alone.
