Mercedes boss Toto Wolff is excited about what is to come from Kimi Antonelli after the youngster's fine showing at the Brazilian Grand Prix.

Antonelli placed second in both the sprint race and the grand prix itself, recording his second podium finish of the season.

In his first year as Mercedes' second-seat driver, Antonelli is seventh in the Drivers' Championship with three races remaining.

The Italian had to hold off Max Verstappen's charge on Sunday, and Wolff believes there are plenty of positives to go off.

"I think all weekend he was strong, from the get-go. It's good to see," Wolff said.

"Maybe it was coming to a track that he didn't know, it's a bit easier.

"Expectations are maybe lower, maybe pressure is not as high as some of the Europeans and then the execution was faultless at the end.

"Being able to fend off Max [who] on a newer and softer tyre, boy, that was really strong and a testament to what's to come.

"There will be more difficult ones, but let's see the next few races. I think we're seeing the young boy becoming a young man and performing."

Though Antonelli's performances dropped off around the halfway point this season, Wolff never had any doubts that the 19-year-old would rediscover his form.

"I was always confident he's going to get the necessary grip," Wolff added.

"That's why it was always clear that Kimi is going to stay with us next year also.

"So there was no doubt that with these complicated cars, the management of the tyres during them is something that you need to learn. And in that respect, that's a great result.

"There was not a single moment of doubt in how he's coming. But I always try to dampen the expectations on him. The Italians talked about the legend Kimi Antonelli after Montreal, after the Miami pole, and that's an additional pressure.

"So let's keep both feet on the ground. He was second, he fended off Max. That was very impressive."
