Huuuugeee crowd at the Hungaroring. I've got the feeling they are in for an epic hour of qualifying.

Not a cloud in the sky as the start of qualifying approaches.

James Hulme: So hope Ferrari's pace in FP3 is real. Excited for quali if it is. Need a big weekend to extend the points gap.

Nick Jordan: I would think having not even driven the car just getting through qualy without hurting himself will be an achievement for di Resta.

Paul di Resta is the first Briton to drive for Williams since Jenson Button in 2000.

He will potentially join Martin Brundle (Belgium GP, 1988), Jonathan Palmer (European GP, 1983), Damien Magee (Swedish GP, 1976) as a one-race British driver for Williams.

The problem that stopped Daniel Ricciardo’s Red Bull in final practice was an engine hydraulics system failure - the same problem that afflicted him in qualifying at Silverstone and left him at the back of the grid. At least this time it happened in practice. It meant Ricciardo did not have the chance to who whether he would have been able to retain his searing pace from Friday.

So far, Red Bull’s hopes seem to rest on the Australian. The fact team-mate Max Verstappen was only just over 0.5secs quicker despite having a whole session, and doing a qualifying simulation run, suggested the Dutchman was still struggling, and team boss Christian Horner confirmed this was the case, adding: “His team-mate’s having an ‘on’ weekend.”

Can Ricciardo mix it with the Ferraris at the front?

Here's a graphic I rattled together highlighting the career stats for Michael Schumacher when he secured the final pole position of his career alongside Lewis Hamilton's stats as they stand now.

If Hamilton takes pole position today then he will have reached 68 career poles in 44 fewer races than Schumacher.

Qualifying gets under way at 13:00 BST and you can listen to commentary on BBC Radio 5 live and online.

So, how about Paul di Resta to take pole position then...

If you fancy predicting the top three for qualifying then head here to do just that.

There's plenty of support for di Resta...

Rich Atkinson: What an opportunity for Paul Di Resta! Great driver. Fingers crossed he nails the rest of the weekend.

Megan Walton: Get well soon Massa! Excited to see Paul Di Resta race. Sat at the first corner in Budapest, prime spot! Can't wait. Bring on quali!

The pressure must be big on Lance Stroll now because he really will not want to be beaten in qualifying by someone who has not raced in Formula 1 for nearly four years.

Mercedes are having a difficult time at the Hungaroring - at least on one-lap pace. Lewis Hamilton and Valtteri Bottas were nowhere in final practice and the team are not sure why they are so far off the pace. The biggest conundrum in that last session was Ferrari’s pace - they have made a big step forward since Friday, when the two teams were pretty evenly matched. But then Ferrari often do, so being close on Friday should have been ringing alarm bells.

The question now, if the lack of pace continues, is what to do. Do Mercedes start at least one of their drivers on the soft tyre, on which Valtteri Bottas was very quick on Friday on the race runs, and run long and try to beat Ferrari that way? That would require using it to set the drivers’ best time in Q2.

Alex Withington: Super sub driver - I'd love to see @F1MikaHakkinen, external In his prime he went toe to toe with Michael Schumacher and won.

Samantha Andrews: Jenson Button! Commentator or driver, or he could just do a triathlon.

Wayne Mullins: Kubica is probably in town for the upcoming test. I'd have him in the car as my super-sub.

If you are just joining us, here's a summary of the big talking points ahead of Hungarian GP qualifying:

• Britain's Paul di Resta steps in for unwell Felipe Massa for qualifying and race
• Di Resta hasn't been in an F1 car for three years
• Sebastian Vettel was fastest in final practice
• Lewis Hamilton, aiming for a record-equalling 68th pole position, was fifth
• Daniel Ricciardo stops in final practice with gearbox problem

Williams deputy team principal Claire Williams, speaking to Sky Sports: "I think Felipe Massa is more upset than anything else. You are tuned in for a race weekend and then you don't race but he has made the right choice.

"I have just sat with Paul di Resta while he was trying to have some lunch. He has been our reserve driver for two years, he sits in every engineers briefing. I have confidence.

"Hindsight is a wonderful thing. We did everything we could yesterday to make sure Felipe was able to take part in Fp3. It is the right thing to do to give your driver the opportunity rather than stand him down.

"We knew coming into the weekend that this isn't the easiest track for the car so it isn't going to be easy for Paul but there's no expectation. We are just pleased to have a driver in the car."

So, Paul Di Resta has it all to do after Felipe Massa’s decision to withdraw because of illness.

The Scot has not raced in F1 since 2013, although he has kept sharp in the DTM German Touring Car Championship, the only hybrid car he has driven is the 2014 Williams and his experience of the 2017 cars is limited to the simulator. So it’s a big ask for him coming straight into qualifying on a track where Williams are clearly struggling.

But nothing to lose, everything to gain, as they say. He’s a quality driver who lost his place in F1 for reasons other than his performance in the cockpit, so it will be interesting to see how he gets on.

Aidy Muttram: Chuffed for Paul di Resta How he's not racing regularly, I don't know. If he can get the car to work, outside chance of Top 10 2moro

Jennifer Harris: Sorry to hear Massa unwell but what a chance for Di Resta. Go Paul, go.
