Lewis Hamilton (4th): "Honestly, it's very hard to realise it at the moment. It's something I dreamed of, but I never in a million years thought I'd be standing here today a five-time World Champion. I never knew that was going to happen and I am just so grateful to everyone who has helped me be here. I want to say a big thank you to all the fans here for making the Mexican Grand Prix as special as it is.
