The Portuguese, who succeeded Jim Jefferies as boss last August, on Saturday oversaw a 5-1 win over Hibernian in the first all-Edinburgh Scottish Cup final since 1896.

Sergio is now out of contract and, with no offer forthcoming from Hearts owner Vladimir Romanov and the club's board, he is poised to return home to Portugal.

"I'm not happy with this situation," Sergio said.

"I think in a moment like this that things should be more clear.

"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.

"To be honest with everybody I don't know if I'm going to be here [next season] or not."

Romanov was at Hampden, dressed in a kilt, to witness Hearts' demolition of their nearest rivals, which extended Hibs' wait for Scottish Cup success into a 111th year, their last success in the competition coming in 1902.

Lithuanian businessman Romanov, who announced earlier this season that the club was for sale after declaring he was disillusioned with football, left Scotland immediately after the final leaving Sergio in limbo.

The Portuguese guided Hearts to a fifth-place finish in the Clydesdale Bank Premier League despite four months of significant salary delays, which included a complaint from the players to the Scottish Premier League.

Hearts have already announced their intentions to cut costs and that midfielder Ian Black will not be offered a contract extension, while forward Rudi Skacel was "99%" sure the final was his last game for the club.

Striker Craig Beattie joined on a short-term contract in February after being released by Swansea and hopes former Sporting Lisbon boss Sergio stays.

Beattie said: "I can't speak highly enough of him tactically and as a man. He's been sensational."

Like Sergio, Beattie is unsure where his future lies.

He added: "I'm certainly open to staying if it's a viable option. We'll sit down with my advisors and the club and see what we're going to do."
