Smooth as you like by Lewis Hamilton. In and out on a fresh set of softs. Back out in third.

Mercedes then call in Nico Rosberg for his second stop.

McLaren's Jenson Button tells BBC Radio 5 live's Tom Clarkson: "I had a failure on the front right, I don't know what it was. 

"The race doesn't matter, it's the weekend that counts. The fans, all my mechanics, people in the pit lane... it was very emotional but an amazing day, amazing weekend and I've really savoured every second of it."

Second stop now for Lewis Hamilton. He pits from the lead.

Romain Grosjean's wheels touch Carlos Sainz's and Grosjean ends up off the track, prompting a rambling whinge over the radio by Grosjean. Didn't understand a word he said.

An even quicker lap by Nico Rosberg as he does a 1:45.822 and the gap between himself and Lewis Hamilton is down to 3.2 seconds. More importantly, he is 10 seconds down the road from Sebastian Vettel, whose third. 

Kristine Kirby: Wonder if now is a good time for Lewis Hamilton to slowww & appreciate the sunset...while cars back up into each other.

Dan Washbourne: Rosberg being lauded for getting into second behind Hamilton, miles away, shows why he just isn't deserving of a world title.

Wasiyullah Budye: Max Verstappen is the future of F1. This guy is an absolute superstar. Love his fearless driving! Legend in making.

Fresh rubber for Kimi Raikkonen and he is back out in eighth BEHIND Daniel Ricciardo. Great call by Red Bull.

Kimi Raikkonen is third at the moment, eight seconds behind Nico Rosberg. 

Meanwhile, Daniel Ricciardo becomes the first of the front runners to make his second stop of the race. He takes on fresh softs and is back out in eighth. 

Hoping to get the jump on Ferrari? They respond as Kimi Raikkonen comes in.

That overtake was Nico Rosberg's season in a nutshell - he did what he had to do.

The nerves needed here, given what is at stake.

Bravo Nico Rosberg.

Edward Everitt: And people say Nico can't do wheel to wheel racing. Come on Nico bring it home!

Nick Hughes: That's what a champion does, great overtake by Nico and fair driving by both.

Nico Rosberg goes even faster with a 1:45.975 to take three tenths of a second out of Lewis Hamilton's advantage.

Mercedes race engineer to Nico Rosberg: "OK Nico, the next few laps are critical - Verstappen is going to the end."

It looked like they were going to collide, they were wheel to wheel with a few millimetres between them. That compromised Max Verstappen into the right-hander of the left-right chicane and it meant he had a slow exit and it was a reasonably easy overtake in the end for Nico Rosberg.

That was brilliant by Nico Rosberg. A driver that can be criticised for rarely taking risks just took on one of the best drivers F1 has seen for years in Max Verstappen. 

Clear of the Red Bull, Rosberg hammers it. He's the fastest man on the track with a 1:46.022 and is 4.7 seconds behind Lewis Hamilton.

Verstappen finally pits for softs and is back out in eighth. He'll be going to the end of the race.

Mercedes race engineer to Nico Rosberg (now second): "OK, now catch the back of Lewis. Good job, good job."

Now or never for Nico Rosberg and he knows it. 

"It's getting difficult now," says Max Verstappen on his ageing tyres. Rosberg makes his move down Turn 8 but Verstappen holds him off initially but can do nothing when Rosberg has another go. 

Great fighting. The move that wins Rosberg the title?
