Atletico Madrid are unwilling to accept a lower offer for Saul Niguez.
Manchester United were hoping the coronavirus pandemic would force Atleti to sell their star midfielder for a reduced price.
However, reports in Spain claim that is not the case.
Marca says Atleti will only accept offers that meet Saul's €150m release clause.
It is unlikely United will be able to afford such a fee given they are also interested in Jadon Sancho, Harry Kane and Jack Grealish.
Any potential move for the Spain international could be based on the sale of Paul Pogba.
The Frenchman is reportedly pushing for a move to Juventus or Real Madrid.
