Paulo Sergio was unhappy with the silence over his future as his Hearts side paraded the Scottish Cup through Edinburgh on Sunday.
The Portuguese coach, who succeeded Jim Jefferies as Hearts manager last August, oversaw a 5-1 win over rivals Hibernian at the weekend in the first all-Edinburgh Scottish Cup final since 1896.
But Sergio is now out of contract and, with no offer forthcoming from Hearts owner Vladimir Romanov and the club's board, he is set to return to Portugal with his future in the balance.
"To be honest with everybody I don't know if I'm going to be here or not," Sergio said.
"Everybody knows I would like to stay but until this moment I don't have anything.
"In this situation what I have to do is to book a flight and return home and see my daughters.
"That's what I'm going to do. I'm here, people are here, but nobody has said anything until this moment, so it's not to me that you have to put the question.
"I'm not happy with this situation. I'm happy with our supporters, with our players, with all we did together in this season in hard conditions.
"But I think in a moment like this that things should be more clear.
"They are managing the club, they do what they want, what they think is normal to do. For me, we are losing too much time."
The uncertainty over his future means Sergio has been unable to plan for next season, which will include Europa League football.
He added: "Of course, normally I would have everything done in this moment. I have nothing done in this moment for next season."
