Brazilian Grand Prix promoter Tama Rohonyi is not worried about the prospect of losing the race at Interlagos.
The Brazilian Grand Prix is so far only listed as provisional for 2017, but Rohonyi insists he would not be too disappointed if the race does not go ahead.
"We have a very old and powerful company here and we'll immediately get another international race for this circuit.
"People come to Interlagos because they are petrolheads and once a year, they want a big international race," he told Autosport. "I'm in the business of running international motor races and if I can't run F1, which I have been running for 42 years, it's like if Pavarotti dies, you get another singer."
"You have an opera house and you have to fill the seats so that's what I'll do. I don't lose sleep over that."
Rohonyi says that the economic situation in Brazil makes hosting the race tough, but he is confident a solution can be found.
"We lost important sponsorship by state companies, the state bank, the oil company, the state trading company and even Shell, which used to be a big client here - but I'm confident we'll be okay."
