The agent of Marcelo Brozović admits the Inter Milan midfielder's contract carries a buyout clause.
The Croatia midfielder has been linked with Tottenham this week.
And Miroslav Bicanin told Vecernji List: "At the moment the most important thing is the total recovery after injury.
"As for next summer, I must say that he is very focused on Inter, although there is a 50 million euro clause.
"If any club should arise with this amount, the Nerazzurri are not entitled to make counterproposals."
