​Kimi Antonelli needs two points in Mexico to be certain of becoming world champion [PA Media]The race that took Kimi Antonelli to the brink of a record-breaking world championship was, in the words of his Mercedes team boss Toto Wolff, “the best he has delivered so far” and “the race of a champion who isn’t the champion yet”.Not yet. Not quite. But so very near.The 20-year-old Italian’s victory in the United States Grand Prix puts him in an impregnable position.Antonelli is so far ahead in the points that the only way he could not win the title in Mexico City next weekend is if either his team-mate George Russell or Ferrari’s Lewis Hamilton win the race. Even then, Antonelli will guarantee the title if he finishes ninth, or 10th if it’s Hamilton.He arrived here thanks to one of the most dominant victories of the season, in a car in which Russell could finish only eighth, albeit hampered by a five-second penalty.While Russell was toiling and failing to pass McLaren’s Oscar Piastri, Antonelli was operating on another level entirely, as he has so often this season.”Exceptional,” Wolff said, “and I think he’s outperformed the car.”Antonelli wins in US but has to wait to secure titleAntonelli came to Austin already in a strong position in the championship, knowing he would clinch the title if he won with Russell finishing lower than eighth and Hamilton lower than fourth.He achieved his part of the bargain but Russell and Hamilton did just enough to keep things alive until this coming weekend. Russell was eighth and Hamilton fourth.Some drivers tighten up when they get this close to achieving their lifetime’s ambition. Not Antonelli. He said he was going to treat this like any other weekend, but it wasn’t just talk. It’s exactly what he did.”He comes in,” Wolff told BBC Sport after the race, in a conversation after finishing his official news conference, “sits on my chair, feet up, and keeps chatting away and saying: ‘This is so funny. I’m not thinking about the championship at all.’ And in a kind of youngish excitement, almost like it’s surreal. And that’s why it’s not so important.”Did Wolff think that was because Antonelli’s lead was so large that he had no need to feel any pressure, or was it innate?”The advantage helps,” he said. “But it’s also innate in him and I don’t think that it’s something to be trained for. He’s not over-thinking it.”Wolff’s claim about this being Antonelli’s best performance so far might surprise anyone who watched him win his home grand prix at Monza from 19th on the grid.When this was pointed out, Wolff replied: “My problem is that I don’t remember past races. So now you’re saying Monza was actually also pretty good, obviously with the advantage of the home crowd and seeing all these tifosi that were a little bit confused, wearing red, and an Italian with the Mercedes outfit up on the podium. And I think we’re going to see more Kimi caps, Mercedes caps next year.”So both of them were pretty good. But the headline that th
