That signing, perhaps one of the biggest driver shocks in living memory, grabbed the world’s attention and laid down a real marker about Ferrari’s ultimate ambitions.

A fresh mood of optimism spread among Ferrari’s loyal tifosi fans, and the presence of chairman John Elkann at its factory to witness the final touches being made to its new SF-24 car ahead of the launch, highlighted a fresh level of enthusiasm at the goings on within Maranello.

It is all part of what Ferrari’s senior management have openly labelled ‘Operation Relaunch’ – a long-term strategic vision aimed at getting the Prancing Horse back to the very front of F1.

But while Hamilton’s signing is perhaps the most public of signs so far of a new era coming for Ferrari, those deeply involved with the F1 team have a slightly different view of the way change is happening.

And for Charles Leclerc in particular, who has been a part of the Ferrari family for years, a defining moment for the team was nothing to do with a new driver arriving – but instead came after an under the radar practice session last year.

He thinks that what happened on the Friday of last August's Dutch Grand Prix was a true game-changer for Ferrari – both in terms of what it learned and how it got everyone lined up.

It was at Zandvoort that, after a challenging first half to the campaign where Leclerc and Carlos Sainz had struggled to deliver answers about the lack of race pace of the SF-23, the team decided to do something different.

Rather than concentrate on tyre preparation for the weekend, instead Ferrari split set-ups completely across Leclerc and Sainz, and spent the entire day focusing on car understanding - evaluating the impact of different downforce levels and mechanical set-ups.
