Ex-Formula One CEO Bernie Ecclestone has claimed the sport's new owners don't want him to attend races on the circuit.
Liberty Media have taken full ownership of the F1 franchise, with Ecclestone ending a career of over 40-years in Formula One when he was removed from his position in January following the takeover.
Chase Carey, the American businessman, took on the CEO position vacated by 86-year-old Ecclestone, with the new management team also consisting of Ross Brawn and Sean Bratches.
Following his departure from the F1 scene, Ecclestone believes he is not welcome at races by the new hierarchy.
Ecclestone told the Daily Mail: "Chase sent a message to one of the girls in the office to tell me that they haven't got so many offices at the circuits, only what the race promoter gives them.
"There are three of them [Carey, Bratches and Brawn] so the three offices are being used. So basically they don't want me to come to races. It would have been just as easy to have said that to me. Anyway, I have obliged them."
Eccleston also feels the new management haven't taken the sport forward.
He continued: "They haven't done anything yet as far as I can see. They said they wouldn't talk, they would act. They said I talked before doing anything. I didn't. I got things done quietly. All they do is talk. They said they wanted six races in America, for example.
"If I say I am going to whack someone next time I see them, I'd better bloody well do it. Chase had preconceived ideas of what needed to be done. But now he's on board, it isn't quite as easy as he thought. So I feel sorry for him."
Discussing the current season and the race for the title, the former Motorsport mogul has backed fellow Brit Lewis Hamilton to clinch the Drivers' Championship in the US Grand Prix on Sunday.
"Lewis will win it in Austin next race," Ecclestone predicted.
"He has driven superbly this season, while Ferrari awoke and then fell asleep."
