Oliver Bearman is one of handful of drivers yet to pit, but now the Haas man heads in - and almost ends up in a bit of bother. He manages to slow down his car before he picks up a penalty, and gets back on track in P14.
Lando Norris makes his way, but he just goes a bit too far in front of his crew, making it a slower stop than usual. The reigning world champion rejoins the track in fifth place, just ahead of team-mate Oscar Piastri.

Just thinking about Ferrari's options here. Lewis Hamilton is very quick, Charles Leclerc is now very frustrated, stuck behind Max Verstappen after the penalty that dropped him back after the pit stops, he is now in that situation where he now can't move forward, if he carries on to the chequered flag, it is likely to finish this way.
The fastest stopwatch is not leaving Lewis Hamilton's name anytime soon, as the seven-time world champion tries to chase down Ferrari team-mate Charles Leclerc from fifth place.
McLaren are all in position to receive world champion Lando Norris for his pit stop.
Surrogate dad Pete Bonnington is on the radio to Kimi Antonelli to say the Italian's lap times are looking really good. The 20-year-old is eight seconds clear of Lando Norris in second and 11 seconds free of third place Max Verstappen, who has pitted already.

It is the worst feeling in the world when you are in those pit stops and having to wait because everything about pit stop training is speed, it is about getting it done now, as fast as you can and you have to hurry up and wait. It is just the most painful process.
The title is getting closer and closer for Kimi Antonelli. With Lewis Hamilton in fifth and George Russell in eighth, the champagne will be popping for a title celebration at the chequered flag if things continue to go his way.
Antonelli is leading Lando Norris, who will be handing over the championship baton, by 8.3 seconds.

Right now Kimi is laughing in his car, the whole time because he knows he has got this covered, barring any mechanical issues, he's really happy right now.
Mercedes are stood like statues as George Russell stays pit for 10 seconds. The penalty has been served, so off he goes to rejoin the action in eighth place.
Kimi Antonelli has stayed out and is leading this from Lando Norris and the Red Bull of Max Verstappen.

Going back on the Max Verstappen Charles Leclerc battle, what they are now on, effectively, is the same strategy, albeit on a different tyre but they are on the same pit stop strategy to the end of the grand prix. Either they can both go to the end, in which case Max just has to hold him back or the car behind, currently Leclerc, could potentially if he is struggling to get past opt for a two stop in about 15-20 laps or so, get back on a set of soft tyres and try and get past him that way.
Lewis Hamilton is banking the fastest laps on his fresh rubber from sixth place, but George Russell is feeling the heat from the McLaren of world champion Lando Norris. Neither of those drivers haved pitted yet, and Russell has a 10-second penalty to serve for causing a collision.
So, a bit of magic by Max Verstappen and that should be enough to keep the Ferrari of Charles Leclerc off his rear wing. Lando Norris has been asking what the strategy options are as he sits in third place on his starting soft tyres.
