It shows the power of the undercut, everybody that has pitted early has gained positions.

1. Alex Albon (Williams)

2. Oscar Piastri (McLaren)

3. George Russell (Mercedes)

4. Lando Norris (McLaren)

5. Lance Stroll (Aston Martin)

Now Charles Leclerc and Lando Norris head in to the pits. Williams' Alex Albon is staying out and leading the race as Oscar Piastri moves up to second.

With Lando Norris doing an extra lap compared to his team-mate, he's now under pressure from the Mercedes of George Russell, who pitted earlier. The McLaren man is passed by Russell and is now in fourth place.

Race leader Oscar Piastri is next to change the mediums for the hards. The Australian is done and dusted and rejoins the action in fourth spot. Lando Norris stays out and is now ahead of the pack, with Charles Leclerc, who also hasn't stopped, in second.

Jeremiah Kariuki: The fast start by Norris states his intention not just to try and win the race but also maintain the Championship lead.

The pit window has been flung open now, and next to come in is Lewis Hamilton and Max Verstappen. Hard compounds for the pair of multiple world champions - Hamilton comes out in 10th and Verstappen two places lower.

George Russell reckons a one stop is doable.

What Charles Leclerc is able to do at the moment is he's building that buffer to Max Verstappen so when he comes in to do that wing change he's got the potential to stay ahead.

Rookies Kimi Antonelli and Isack Hadjar are into the pits to dump their medium tyres for hards. As Italian Antonelli comes out, however, the Racing Bulls of Yuki Tsunoda, who pitted a lap earlier, overtakes the Mercedes.

Tsunoda is 13th and Antonelli is 14th.

Charles Leclerc seems happy with his pace and he's keeping with Lewis Hamilton even with a front wing that is nearly drooping and scraping on the ground.

He's lost downforce but it doesn't seem to affecting him as much as I thought.

McLaren have 'C' in the plan alphabet. The letter belongs to race leader Oscar Piastri, who is now two seconds clear of team-mate Lando Norris.

Yuki Tsunoda at Racing Bulls, the Haas of Esteban Ocon and Jack Doohan at Alpine have all stopped for some hard tyres.

The Alpine of Pierre Gasly comes in to change the medium tyres over to the hard compound. Ferrari are preparing themselves for a car to come in, but when that will be we don't know.

Oscar Piastri advantage over McLaren team-mate Lando Norris is 1.9 seconds, with George Russell over four seconds behind Piastri in the Mercedes.

Charles Leclerc is nursing his sick front wing in fifth, debating with his Ferrari engineer over what plan they should settle with. A or B?

The estimation with clear air is that it can be an advantage by as much as half a second a lap.

Birthday boy Alex Albon is straight to the point with his Williams pit wall. Albon has dropped out of the top 10 and is now in 11th place but he tells his engineer his tyres are fine, fine I tells ya!

The Racing Bulls pit wall is wise to tell Yuki Tsunoda to calm down, as Lando Norris has just been on the phone to McLaren to say his front left tyre is struggling already.

Yuki Tsunoda has moved up to eighth place from ninth but the Japanese driver wants to push the front of his Racing Bulls hard. His engineer is dead against it. Keep it things cool, Yuki.

This track is really hard on that front left tyre so if you've got a car that typically has more understeer because you've lost those points of downforce can make the graining even worse.

I expect Charles Leclerc to be overusing those front tyres, we might see him being an earlier stop than what he originally thought.

Oscar Piastri survived the race start and now the Australian is controlling the race from McLaren team-mate Lando Norris. George Russell is staying in third place with former Mercedes buddy Lewis Hamilton just behind in fourth.

Josh Earl: Yes Lewis, that's the start we needed! Come on!

Jack Lovatt: New team, same quality team work from Lewis Hamilton

The replays show Gabriel Bortoleto was also caught up in some drama with the Haas of Oliver Bearman. The Brazilian ended up in the gravel and is now down in 19th place. Briton Bearman is 15th.
