You have to feel so, so bad for Charles Leclerc, his power is dropping, his lead is fading fast.

Lap 47/57
You have to feel so, so bad for Charles Leclerc, his power is dropping, his lead is fading fast.
Hamilton is closing all the time.
Lap 47/57
Hamilton was 20 seconds off the lead, that has drastically dropped to seven seconds.
Wait a minute! Wait a minute!
"Something strange with the engine," says Leclerc.
Lap 46/57
In all the Hamilton-Vettel carnage, let's not forget that Charles Leclerc is closing in on his first ever win, in only his 23rd race. What a talent.
Will Ferrari live to regret not letting him attack Vettel in Australia when Leclerc was told to hold fifth and not attack the German, who had been fourth at the time?
Lap 44/57
Sebastian Vettel is in damage-limitation mode and is doing a good job, bolting himself up to fifth from ninth.
Nico Hulkenberg is sixth, after starting 17th. It's a good points haul for Renault, despite both of their cars hitting each other as Ricciardo is currently seventh.
Reece: Oh Vettel......that is so poor. How many times does he spin it when he's under pressure? Threw away a podium. He's just bottled it all.
Euan: I was thinking that if Leclerc was ahead or nipping at his heels by the halfway stage of the season, Vettel would start to crumble. I didn't expect it at halfway through the second race.
Lap 43/57

Lap 42/57
"What was that, he hit me, I gave him so much space," says Renault's Nico Hulkenberg as his team-mate Daniel Riccardo gave him a tap.
Lap 42/57
So Charles Leclerc's lead is now nine seconds over Lewis Hamilton, with Valtteri Bottas third and Max Verstappen fourth.
Vettel's spin, front wing coming off, pit stop carnage has left him ninth, but he has since gone past former team-mate Kimi Raikkonen and Lando Norris so that's seventh for Vettel.

Team-mates colliding is not what Renault team principal Cyril Abiteboul will need!

This is another fascinating inter-team dynamic that we were looking at at the start of the year.
Lap 40/57
Rule 1: Don't hit your team-mate. Don't hit your team-mate. Don't hit your team-mate.
The Renault pair of Nico Hulkenberg and Daniel Ricciardo touch. Amazingly they both seem to have got away with it.
Both are still in the race, lucky, lucky boys.
Vettel: "Ohhh my tyres, box."
Yes, and your front wing!

Lap 39/57
We've seen Vettel's car lift off the ground and a huge amount of sparks from his car as his front wing rips off. Back to the pits to get another one. Vettel was second, now he is down to ninth.

It's a rookie mistake for Vettel - Monza, Suzuka, USA they're all similar mistakes.
Hamilton gets past on the outside, Vettel tries to hold on to the place, he spins, he rips his tyres apart as well. The front wing is off as well. Disaster for Vettel.
