Kimi Antonelli sealed his spot in the Formula 1 history books with a maiden pole position and victory at the Chinese Grand Prix, but attention has swiftly turned to whether he is ready to challenge his Mercedes team-mate George Russell for the 2026 drivers' title.
The 19-year-old became the youngest driver to claim a grand prix pole position on Saturday, and backed it up with a (mostly) mature display on Sunday to win the 56-lap race.
Mercedes' early-season speed, which has seen them secure back-to-back one-twos to start the year, has established both the team and their drivers as the championship favourites.
Russell had largely had things all his own way in Australia and then at the start of the weekend in China as he won Saturday's Sprint, but he was left exposed by some gremlins in qualifying and was unable to recover from there.
Any thoughts that the Brit might be on course for a dominant march to his maiden title have been put on hold for now by Antonelli's win, while it must also be noted that Ferrari have pushed Mercedes hard at various stages of the opening two rounds and retain their own aspirations.
Just a matter of minutes after the champagne had been sprayed on the Shanghai podium, attention was already turning to the debate over whether Antonelli can stay the course with Russell.
Expectations have been high for Antonelli since he was fast-tracked into a Mercedes seat by team boss Toto Wolff as Lewis Hamilton's replacement when the seven-time world champion decided to leave for Ferrari.
Billed as a generational talent - and treated like one by his team - Antonelli showed early promise in his rookie campaign before a mid-season slump raised doubts over whether Mercedes had rushed the process.
A return to form in the latter stages of 2025 levelled his season out to somewhere around par, but Mercedes starting the new season with the fastest car has significantly raised the stakes.
It was a mixed start for him in Australia as a huge crash in final practice almost prevented him from participating in qualifying, before he recovered to take second on the grid and in the race.
He remained unable to match Russell in the Shanghai Sprint events, but then an opportunity arose when the Brit suffered a technical issue in Q3 that left him time for only one rushed run at the end of the session, while Antonelli had two more regular shots at pole.
Antonelli seized the moment, beating Russell by a couple of tenths, providing further evidence in the process that he was not carrying any mental scars from his Melbourne crash.
Antonelli's first two races of the season had been ruined by terrible starts as he dropped back down the field from second on the grid in both Melbourne and the China Sprint.
He was therefore under huge pressure to avoid the same thing happening again on Sunday, with even more to lose on this occasion.
While Ferrari's large early-season advantage with starts told once more as Lewis Hamilton surged into the lead around the outside, Antonelli's decision to focus on covering his team-mate on the inside was extremely shrewd.
Ferrari have been jumping Mercedes - and anyone else in front of them - off the line, but Mercedes have shown enough pace to come back during races, so Antonelli's main rival was always likely to be Russell.
While he said after the race that he had made "a mistake" by focusing too much on Russell, keeping his team-mate behind off the line was perhaps the most crucial moment of the race for Antonelli.
Antonelli quickly passed Hamilton and then held the lead from Russell. A poor rolling restart for Russell after an early Safety Car saw him get held up by the Ferraris, allowing Antonelli to build a lead that all but ensured victory.
There was no further Safety Car to bring Antonelli under pressure from Russell, but he did threaten to throw the victory away himself.
Three laps from the end, with his lead approaching 10 seconds, Antonelli locked up at the end of the main straight and went off track. It only cost him a couple of seconds, and he would take the chequered flag a few minutes later.
That moment showed a couple of things. The first was immaturity, in putting his victory at risk when it was almost completely wrapped up. The second was that he wanted to send a message to Russell and make the winning margin as large as possible.
That was evident when he was still swinging his car around the corners of the Shanghai International Circuit on the final lap, perhaps showing a ruthless drive that isn't always visible through the boyish charm displayed in his media appearances.
Antonelli said immediately after the race: "George is an incredible driver, very strong on all aspects, so it's going to take a lot to beat him. But it's a great opportunity to be working with him as well because I have been learning a lot from him.
"Looking forward to the rest of the season now. I always focus race by race, so we'll see where we end up at the end of the year."
Wolff has put his own reputation on the line by selecting Antonelli when far safer options were available, and the Austrian has appeared to play a hands-on role in managing his protégé.
It was therefore little surprise that his reaction on Sunday was to attempt to relieve the pressure on Antonelli, particularly from motorsport-mad Italy, where the result was already generating huge excitement.
Wolff said: "You can kind of see the hype that is going to start now, especially in Italy. I see already the headlines, 'world champion' or whatever. That's really not good because those mistakes are going to come.
"He's just a kid, so it's too early to even think about a championship."
Speaking to Your Site F1, Wolff added: "I think it's maybe come earlier than I thought.
"Last year we said that it's going to be a very difficult year with many ups and downs and mistakes.
"Then, bang, second race (of 2026). He has controlled it in the front, he has driven very well today, so he's probably a little bit better than the trajectory I thought."
Former F1 world champion and Your Site pundit Jacques Villeneuve has been critical of Antonelli in the past, but said before his win that the Italian could become "a force to be reckoned with."
Villeneuve pointed out that if Mercedes remain dominant, Antonelli can stay in the title hunt by being patient and picking off opportunities to beat Russell when they arise.
Speaking before Sunday's race, the 1997 world champion said: "Antonelli knows that he's a little bit slower than Russell right now, that he has to push harder.
"He needs to make a step to put himself on the same level on a constant basis, which is not the case right now.
"But that means he should still grab second places in most races at the moment, so the gap should never get too big.
"If he makes that step during the season, then he'll be a force to be reckoned with."
With Russell just four points ahead of Antonelli going into the Japanese Grand Prix in two weeks' time, the pressure is all on the Brit to respond.
