The seven-time world champion has enjoyed a trophy-laden spell at Mercedes, winning six of his drivers' titles whilst racing for the iconic team, and at Silverstone this past weekend, finally put an end to his longest run in F1 without a victory.
The 17-year-old enhanced his stellar reputation at the weekend, winning the Formula 2 sprint race at Silverstone ahead of the British Grand Prix, and in doing so, tasted victory in F2 for the first time.
Antonelli has shown glimpses of his pace this year but has failed to live up to the lofty expectations placed on his young shoulders. His composed performance in the rain at Silverstone on Saturday, however, underlined his quality and proved he has the maturity to match his undoubted talent.
Wolff has already admitted he has been impressed by Antonelli's progress and is keeping a watchful eye over his development as he looks to secure the team's long-term future.
Speaking to the media after his emotional maiden victory, Antonelli revealed he has found it difficult to cope with the added pressure of being considered heir to Hamilton's Mercedes throne.
“Not always do I cope really well with pressure," he said. "Obviously, this season has been a big amount of pressure, to be honest.
“But I can say today that I coped with it pretty well. There are still some improvements because sometimes I still make some mistakes.
“For example, yesterday in qualifying, I did a mistake on my lap and lost quite a bit of time.
"So definitely, sometimes I still don’t perform as I could, but I’m trying every time to cope as best as I can with the pressure, and I think today was really the showcase.
“It was a big relief for me because it really takes a lot of weight from my shoulders."
