On Verstappen's steering issue..."It's more and more difficult to steer with speed.
"From what we can see the situation is stable. It's not getting any worse. It is what it is. You may have to live with it, if it becomes undriveable obviously you know the situation."
The marshals are desperately trying to put out the flames of Pierre Gasly's Alpha Tauri and we're still behind the safety car. Gasly, thankfully, is absolutely fine and jumped out quickly.
Red Bull are being a bit cryptic over team radio as they tell Max Verstappen they know what the problem is with his steering, but knowing everyone is listening in, decide to not tell anyone.

Argyle Jack: Mick's in p10 ! cmon double Haas points.
Andrew Priestley: Oh look, the Safety Car allowed all lapped cars to unlap themselves…
Thought a few of you might mention the unlapping after what happening in Abu Dhabi last year.
"Come on - the safety car must go quicker. It gives me a big disadvantage by going slow like this."
That's a double points finish for Haas as it stands. We're going to have a seven or eight-lap sprint for the win. Mercedes could still be in contention here if there is chaos ahead of them.

"Keep checking what it could be, it's like something is stuck or whatever."
Image source, Getty ImagesVerstappen is still complaining about a steering issue. We're still under the safety car and Leclerc has gone on to the soft tyres.
The field will be bunched up, but Leclerc is now on fresher tyres than second-placed Verstappen, who is reporting problems with his steering.
New season, same brilliant F1.

It's not a free pit stop but it as good as for Charles Leclerc.
It looks like Pierre Gasly's engine has had a very big hiccup, that's not nice.

This is disastrous for all those fans of McLaren. So many people have fallen in love with McLaren, the story last year was so romantic. But something has gone horribly wrong for McLaren over the winter.
That safety car could see Charles Leclerc dive in for a near-free pit stop.
He's OK and springs out the car, but that be a decisive moment in this race for the leaders.
"We have less deg [degradation] than Verstappen."
