The crowd are singing Rosberg's name. He's beaming. Such a contrast from seven days ago, hey?

Get all the latest on Formula 1: calendar, results and standings.
Nigel Mansell is doing the podium interviews. He calls the drivers off the podium so they can be more easily seen by the crowd.
Fans of hat-based controversy will be pleased to learn that there are sombreros being liberally distributed.
Rosberg wins, with Hamilton second. Valtteri Bottas takes third place.
Rosberg cruises into his final lap now, and the crowd applaud.
Scruffy, scrappy lap from Hamilton - the gap is now over 1.6 seconds and that's probably it.
The Lotuses are having a bit of a battle for 10th place. Maldonado with a point to prove as always.
Intriguing as Hamilton continues to close to gap to Rosberg.
Daniel Ricciardo is being urged to keep up with Dany Kvyat, 1.7 seconds ahead of him.
Pastor Maldonado teases the world by pretending he is going to crash into a wall then recovering it at the last.
Yes, the clouds are closing in, but that forecast for storms doesn't seem set to be coming true.
"My brakes are finished!" announces Nasr as he retires his car. Jenson could have told you that two laps ago.
Rosberg gets away well, Hamilton tucks in behind, Bottas moves into third.
The safety car has gone! We're racing again.
Jenson Button reports a brake fire in Nasr's car just in front of him.
Vettel has been apologising to his team over the radio. Very odd, remains to be seen how much was a technical problem and how much was driver error.
Meanwhile, the gaps are closing up and the Mercedeses are going to go into a shoot-out when the safety car goes away.
That Vettel incident was really odd. He was trying to turn the steering wheel but just ended up going straight on.
Several drivers now making the quick call to pit while the safety car is out.
Oh, Seb. The safety car is out because Sebastian Vettel is into the barriers. "I'm OK. I crashed. Sorry."
And on those fresh tyres, Hamilton logs the quickest lap so far.
"Please check those tyres and let me know. I want some feedback." Lewis Hamilton wants a full analysis of those tyres which have just been taken off his car - he's still unconvinced he needed to come in.
Hamilton seems to be puzzled about being called in.
"We're converting to Plan B!" comes the Mercedes message over the radio to Lewis Hamilton.
Now. Is this a strategy or is this a problem? Nico Rosberg is in the pits!
"Don't tell me any more!" squeals Nico Rosberg over the radio. He cares not to learn about the gap between him and his team-mate.
I can report that the debris has now been removed. Phew. Meanwhile, Vettel is seeing some blue flags and is grossly displeased. He's not enjoying his day, is he?
Hmm, a couple of the drivers are reporting debris at Turn 10. Wonder what that might be, and whether they're going to bring out the virtual safety car so it can be cleared.
The two Mercedes are separated by about two and a half seconds, and then there's a whacking 20-second gap between them and the leading Red Bull.
There's a big cheer as Carlos Sainz locks up into the corner and veers off into the grass, cutting the corner - and then allows Sergio Perez through right in front of the grandstand.
Rosberg did stay out there for a while, meaning his team-mate also had to delay his stop.
Jenson Button finally comes into the pits. He's the last one to stop.
Both the Mercedes have now pitted and have resumed their places at the front of the pack.
No further action for that Raikkonen/Bottas drama either.
The stewards are investigating that, as you might expect.
Collision! Raikkonen is clipped, and out of the race - Bottas was making a move past him. These two have yet another heated encounter.
Vettel reports a flat spot - he says he's going to continue but he's not a happy man.
Vettel goes for a spin at the Ss! Not sure what happened there. He's got himself back on track, but he's dropped down to 16th after all that work he did overtaking following the first-lap pit stop.
Poor Jenson Button is being overtaken and with great ease. Those Mercedes-powered cars laugh in the face of Honda's power.
Nico Rosberg logs the fastest lap so far.
Perez is asked if he can keep out there for another five laps. "At this pace," he concurs.
Daniel Ricciardo is reporting problems with the rear of the car, but he says he can hang on for a bit longer.
Valtteri Bottas is into the pits - first one in for a strategic stop.
The stewards have ruled that no further action is necessary about that collision between Ricciardo and Vettel in the opening lap.
Kimi Raikkonen is asked to do something if possible about the heat in his brakes. His response is not recorded.
Massa is chasing Max Verstappen - the Williams is likely to be much quicker down those straights if he can actually take advantage.
Alonso throws his gloves to his team as he climbs out of the car. What a terrible season.
"OK, Fernando, retire the car." Oh, poor Fernando Alonso. He's lost his gears, he has no power, and it's a retirement in the first lap for McLaren.
Daniel Ricciardo has had some contact with Sebastian Vettel, and the Ferrari has picked up a puncture.
Hamilton is using the sides of the track, trying to find his way around his team-mate Rosberg.
Lights out. We're racing!
It is very, very noisy at this track. They're whooping for Sergio Perez, of course, but all the drivers will get a kick from this atmosphere.
There are small children on the grid singing, planes flying overhead, and a bugle playing with a huge drum accompaniment. It's all very exciting.
If you missed qualifying, you can catch up here.
Good evening, all, and welcome to our LIVE coverage of the Mexican Grand Prix. Can Nico Rosberg reclaim some dignity after last week? He starts on pole.
