Crossing the line on Sunday in Sochi was a really amazing moment. To win the very first Formula 1 Russian Grand Prix and help the team achieve the first Constructors' Championship for Mercedes-Benz with a one-two finish - it couldn't have got much better. 

When I went to the factories in Brackley and Brixworth the week afterwards, the atmosphere was just awesome. Everybody has worked so hard to achieve this title and they all deserve to savour the moment. Of course, we still have three races left to decide the Drivers' Championship - starting in Austin, which is one of the best weekends of the year. 

A lot of the American side of my family come to the race, plus I won the first ever Formula One Grand Prix at the circuit back in 2012, so it's a special one for me. I really enjoy going there and I'm looking forward to another great race - hopefully ending up with another Stetson hat on the top step of the podium!
