Formula One racer Yuki Tsunoda thinks it will take time to reap the benefits from working with a new sports psychologist assigned to him by Red Bull, he said on Thursday.

The 22-year-old, who drives for Red Bull's sister team AlphaTauri, has become a fan favorite for his outbursts on the team radio during races and candid comments about the sport.

"I don’t know currently if it’s working well or not," Tsunoda told reporters at the Austrian Grand Prix.
