George Russell
George Russell is still baby-faced at 20 so there's no surprise the Brit looked as young as he did at 10.
In 2009, Russell was still karting and would win the MSA British & British Open championships that year.
Single-seater would come in 2014, before winning the F2 championships last year and earning him a seat at Williams.
Robert Kubica
Robert Kubica may have lost a lot of his hair in the last decade, but that won't matter if he's retained his racing talent. After being out of a full-time drive since his 2011 rallying accident, Kubica returns to F1 for Williams.
In 2009, (when he apparently loved awful sunglasses) Formula 1's only ever Polish driver was preparing for another season at BMW Sauber, after challenging for the 2008 title.
That campaign would be a disaster for the 24-year-old, the Swiss-German outfit producing a rubbish car that only managed a single podium in Brazil.
