Midfielder Jack Grealish extended his contract with Aston Villa in September and the agreement will expire at the end of the 2024/25 season.
Manchester United remain interested in Aston Villa midfielder.
A potential transfer of the 25-year-old England player would require a significant outlay.
Aston Villa is valuing the player at £90 million, reports The Athletic.
Manchester United was seriously interested in Grealish last summer, but the then £70 million price tag served as a barrier to a transfer. The club eventually acquired midfielder Donny van de Beek.
Next summer midfielder Paul Pogba could leave the team and as such, Man United is looking at options to sign a high-profile newcomer.
In 15 Premier League games this season Grealish has scored 12 (5+7) goals plus assists.
