Bagnaia will claim his first MotoGP championship if he finishes P14 or higher, or if Quartararo doesn’t win.
The Ducati rider qualified eighth, with the reigning Yamaha champion starting fourth.
Bagnaia joked about teammate Miller: “I won’t pay anyone! Anyone can be my teammate for this race.
“It’s hard to do a strategy because it’s impossible to predict what will happen.
“Maybe I have to take risks in the first two or three laps to be able to handle it.
“I just say” [to the team] that if Fabio is close to me, or behind me, then [the Ducati team should tell me on the pit board] and then I decide what to do.”
Bagnaia said: “My thing tomorrow is not to win – just be calm, understand. I will take risks in the beginning to get a hole. But then just be smart.”
When asked who would win the race, he replied: “I don’t know! Jorge Martin was very competitive. Miguel Oliveira was so competitive. Marc Marquez, Quartararo…
“I’ll just try not to be outside the top 14.”
Bagnaia said of his performance in qualifying: “I certainly expected more. We struggled with the hunch. You feel less, but can brake harder – that’s strange.
“On this track it doesn’t help me. We are competitive with used tires.
“The ideas my team has are good. They can help me.”
