Currently, McLaren are clearly at an advantage, while Red Bull are still searching. "You can tell that he does not have more of a clear advantage," says Andretti. "He doesn't need an advantage, by the way. He's good enough. For us watching, it's best if he doesn't, because he fights," he laughs.

"Watch him, it's really better to watch him fight back than to 'oh, he's gone. Nobody can touch him'."

Red Bull are having a more difficult season than in previous years, and according to Andretti, this could partly be due to the departure of top designer Adrian Newey to Aston Martin.

"I don't know if it's coincidence or what, but ever since Adrian Newey left the team, something seemed like something was missing," states the 85-year-old American. "I know Adrian very well. He's the best engineer I ever worked with. I suppose so. He was in IndyCar with me in ’87, so I know his value, and he has a record to show for what he's done with every team he's been with."

Although Andretti does not want to speculate about internal matters at Red Bull, he adds: "So again, but it is what it is. Just the events and whatever happened. We all know. But from where I sit, I think that's part of the issue. If they would express themselves openly, they would say the same thing, especially Jos is the other, I think. But then again, it's not my business."
