Despite enduring a largely disappointing final campaign at Mercedes, Hamilton has offered several reminders of his supreme talent, most notably at Silverstone where he clinched an emotional victory - his first since December 2021.
Leclerc, meanwhile, has enjoyed a more consistent season, securing seven podium finishes and two race wins, the most recent of which coming in Monza last month.
His form likely won't be enough to overhaul either Lando Norris or Max Verstappen at the top of the standings, but a third-place finish would provide grounds for optimism going into next season alongside Hamilton.
Rivalry takes shock twist
The Monegasque has spoken of his intention to develop a positive relationship with his future team-mate, previously revealing they have already held private conversations about a wide range of common interests, including music, fashion, and their pet dogs.
Roscoe has accompanied Hamilton to a number of grands prix this season, while Leclerc's pup Leo became a social media sensation after being introduced to the world earlier this year.
But just months before Leo and Roscoe team up, Ferrari chief Vasseur has suggested another way the pair could become further acquainted.
Speaking at an event alongside Leclerc, the Frenchman jokingly promised to set up a fight between the two dogs next season, much to the amusement of his stunned star driver.
