Max Verstappen's father is confident that the 20-year-old has selected a true "top team" to race for through 2020.
The young Dutch sensation had been linked with potential moves to Mercedes or Ferrari, but instead extended his stay at Red Bull for the next three years.
Former F1 driver Jos Verstappen, Max's father and co-manager, said that he is comfortable with that choice.
"The team has moved heaven and earth to become more competitive again," Verstappen told Ziggo Sport Totaal.
"When you look at the state of the car at the beginning of the season and how good it is now, that answers the question of what makes a top team.
"And all the changes made fit wonderfully with Max's driving style, which is noticeable on the stopwatch."
Verstappen snr, who raced for teams including Benetton and Minardi, also thinks that Max can end the 2017 season on a high.
"In Brazil we hope for a little rain, and then Max can show what he can do, as he managed last year," he said.
"I guess in qualifying the other top teams will be a little stronger, but in the race Red Bull should be able to keep up."
Verstappen is sixth in the 2017 driver rankings with two races to go.
