Max Verstappen says he is ignoring any talk about his mental strength ahead of his F1 debut in 2015 as he feels it is "bulls**t".

With Daniil Kvyat moving to Red Bull and Verstappen himself already having taken Jean-Eric Vergne's seat, Verstappen is likely to form part of an inexperienced driver line-up at Toro Rosso next season. However, the 17-year-old says he isn't expecting the challenge to be a tough one mentally as it's not an area he gives much credit to.



"I have no problems at all with [mental strength]!" Verstappen told the Toro Rosso website. "I'm really relaxed and I don't want to think about mental stress, or how strong you are mentally because, to be honest, I find it a bit bulls**t."

And Verstappen says he takes confidence ahead of his step up to F1 from how quickly he got up to speed in an F3 car this season.

"Of course before you jump in the car you don't know what to expect. But after I did a few laps [in the F3 car], I started to feel comfortable. You start to feel the limits a bit. It's completely different to go karts. I mean, the braking pedal, the throttle application, how you sit in the car, the view. That was the main difference really. But from the beginning we were quite fast, so I adapted quite well."
