"It's a fantastic feeling," he told Sky Sports F1. "[It's] been an incredible year. Lots of great races, super proud of the job from the team. It's been so enjoyable to be part of that group of people.
"To be a three-time world champion is just incredible. We will keep on pushing, doing the best we can.
"Today was quite an exciting race, a bit of a shame with the Safety Cars, but overall it was fun out there. [I'm] just incredibly happy at the moment."
Verstappen: I couldn't catch Piastri
On Piastri's maiden victory in F1, Verstappen admitted that he simply wasn't able to catch the McLaren driver.
“Yeah he did a great race," he said. "It was not, I think that easy because we were on the medium tyres and there were some soft starters around us and they had a bit more grip in the beginning.
"But yeah he did very well, I tried everything I could to try and catch up but we came short at the end.
“We’ll just see what happens. I’m enjoying the moment and hopefully of course we can keep this momentum going forward.”
