The 39-year-old stunned the Formula 1 world back in February of this year, announcing that he was calling time on an incredibly successful spell at the Brackley-based outfit to join fierce rivals Ferrari from next season.
Since joining Mercedes in 2013, Hamilton has collected six of his seven world titles - the other coming at McLaren in 2008 - and created history by smashing the record for the most race wins.
The last of his 103 victories, however, came back in late 2021, with the Brit struggling to keep up with the dominant Max Verstappen at Red Bull.
Hamilton - for so long a regular feature on top of the F1 podium - has failed to finish in the top three in 2024, while team-mate George Russell has only managed to secure a season-best result of fifth.
The 17-year-old is already on the books at Mercedes as a junior team driver, and speaking ahead of this weekend's Emilia-Romagna Grand Prix, Hamilton has given the Italian his vote of confidence, saying he'd take on the youngster if the choice was up to him.
