AC Milan have fears over the contract of Suso amid links with Liverpool and Spurs, according to a report.
Suso has established himself as a star at Milan, having been allowed to leave Liverpool in January 2015.
The 24-year-old has been linked with a return to Anfield, while Spurs and Chelsea have also been credited with interest.
According to Calciomercato.com, Milan are beginning to sweat about the situation surrounding the Spaniard.
Club director Leonardo would like to “resolve the issue related to the release clause, set at around €40million”.
Suso currently has a deal at San Siro until 2022, and the Rossoneri hierarchy are scared that a team in the Premier League will pay that clause, with deals such as the €39m Everton paid for Richarlison proving their fears.
Suso and his agent Lucci apparently remain happy with the current deal and clause, and while the player is happy at Milan, his club are still determined to agree a deal with an increased clause due to interest from abroad.
