Benfica president Luis Felipe Vieira is determined that defender Victor Lindelof will not leave the Estadio da Luz for a fee below his €30m release clause.
Chelsea have been strongly linked with moving for the tough-tackling defender, but Benfica have yet to receive an official approach from the Premier League side.
And the Blues appear likely to have to splash out the full €30m total of Lindelof's release clause if they are to take him to Stamford Bridge.
Indeed, according to Portuguese sports daily A Bola, Vieira is not willing to negotiate on the Swedish defender's price tag as he wants the full €30m to be paid.
Benfica signed Lindelof from Swedish outfit Vasteras SK in 2012 and he progressed through the club's B team to the senior side.

His development has not gone unnoticed and Lindelof was handed his senior Sweden debut earlier this year and now has six caps for his country to his name.
Lindelof has won two Portuguese top flight titles with Benfica.
