[Lewis Hamilton] pulls that red Ferrari into the pit box, they put on a set of softs, but there is a problem with the front right, it needed another attempt. 4.9 seconds, that's slow.

Now Max Verstappen makes his third stop of the race. He comes out and almost gets in a bit of a tangle with his team-mate Yuki Tsunoda, who initially doesn't pull over to let Verstappen pass before eventually doing so. That might have cost Verstappen a crucial couple of tenths, however.

A slow stop by Lewis Hamilton and is back out in seventh but quite far behind the Mercedes.

I can't see the McLarens not pitting again. The most I could see them doing and I think this would be super out there is you pit one and you leave the other out there, but then which one takes the hit of potentially dropping back.

Red Bull definitely have more pace than McLaren were expecting.

Have Red Bull and Verstappen put the fear of god into McLaren and is there a possibility that they might not pit again, they'll go with the pits they have done and spook McLaren into having to drive fast and put more energy through the tyres.

The Red Bull crew come out and are getting ready for a stop. Or are they? Max Verstappen passes the pit entrance and the crew all wander back into the garage.

Mercedes swap cars as George Russell passes Kimi Antonelli into sixth. Up ahead for Russell are the two Ferraris.

Oscar Piastri continues to find some more time and he's got the gap up to almost four seconds now over Lando Norris.

No additional pit-stops yet from the top three, Max Verstappen has done two compared to Oscar Piastri and Lando Norris who have only done one stop.

Fernando Alonso makes his final stop and is back out on mediums. He returns to the track just behind compatriot Carlos Sainz. Nice for the home fans to see, although not so much the fact they are running in 16th and 17th.

Jeremiah: While Verstappen was overtaking Leclerc, Charles tyres looked worn out and offering nothing. Wonder how bad the tyres are on Hamilton and Russell as they seem to fall further back.

Nulla Pax: I think Max is in with a good chance of the win here. That should not sound surprising, of course.

Currently everyone in the top 10 is on mediums apart from George Russell.

Out in front, Oscar Piastri is pushing and keeping the gap to his team-mate at around three seconds.

In goes George Russell for a new set of soft tyres. He's back out in seventh.

Everyone in the top 10, I think is going to have to pit again, including Max Verstappen who has already pitted twice. As things stand, the gap at the top is 2.7 between Piastri and Norris and 7.6 to Verstappen. This is going to be tight at the end.

Max Verstappen is doing a two-stop so far, both times after he left the pits he set a fastest lap of the race.

He's clearly pushing to catch up to the McLarens but the issue is McLaren can then respond with that pace in a more consistent way.

Charles Leclerc pits from fourth and he is back out on fresh mediums.

Engineer: "McLaren are receiving the threat Max. They realise they have to push on. It's a long way to go for them."

There is a lot of pace still being held internally in these [McLaren] cars, but they are being super careful of the tyres.

Could we have a battle between the McLarens for the race win in the closing stages? It looks to be heading that way as Lando Norris continues to chip away at Oscar Piastri's lead.

Fernando Alonso would love to get into the points at his home race and he's still lurking thereabouts as he is 11th, behind Liam Lawson.
