Andre Onana would only leave Manchester United if any interested club is able to pay the sum £30 million to the Red Devils.
The Red Devils set the asking price and are ready to sell the goalkeeper this summer, but have yet to receive offers.
Daily Mail reports that French Ligue 1 top side, AS Monaco have indicated interest in the Cameroonian but are yet to make offers.
Monaco has now been acquainted with the asking price of the former Inter Milan goalkeeper as Ruben Amorim wants to upgrade his team.
Onana was only able to keep 11 clean sheets in 50 games across competitions last season.
For this reason, Manchester United found themselves in the 15th position in the Premier League table.
They were also defeated by Tottenham Hotspur in the final of the Europa League.
The Red Devils are said to have identified Aston Villa goalkeeper Emiliano Martinez as the possible replacement for Onana at Old Trafford.
