Benfica have told any interested clubs that they must pay £23million for Victor Lindelof.
According to Portuguese publication A Bola, Benfica do not want to let the highly-rated defender leave on the cheap if he happens to have his head turned by a bigger club.
It is believed that Manchester United have been showing considerable interest in the 21-year-old and could make a bid for his services in the summer transfer window.
However, the Sweden international will not come cheap with Benfica refusing to listen to any proposals worth less than the aforementioned £23m.
Further adding to his rising stock, Lindelof was on Tuesday named in Erik Hamren's final 23-man Sweden squad for Euro2016.
