Jeremiah Kariuki: Despite an awful morning for Lewis, this may be his 44th Pole! Easy for him to overcome the odds in a circuit he loves to toy around!
John Howard: Hamilton is one driver that can jump in a car cold and bang in a perfect lap. Ferraris the danger.
Edward Williamson: Sad to say, I can't see Lewis getting pole today. Too much going on distracting him. Reckon it will be Rosberg, Vettel, Hamilton.

Well batted that man.
Williams confident ahead of qualipublished at 17:42 British Summer Time 6 June 2015
Williams Head of Performance Engineering Rob Smedley to BBC Sport: "We have got all the major boxes ticked, so I am reasonably confident. I would like to understand where other people are, but it just means that we will be conservative in qualifying."

James Counter: Hamilton may have been slightly compromised, but he has been faster in FP1 and FP2, he also loves the track.
FP_Passion: Even if Nico gets the pole, Lewis will be close... so anything can happen on Sunday!
James: Kimi is looking good for first row, second row at least.

The following day, he won his maiden grand prix.

F1 Rewind was a belter today, what?
Suzuka 1989, Monaco 1992 and Donington 1993, all enveloped in the creamy goodness of an interview with Murray Walker. That's as good as it gets really.
So why, I'm asking myself, did I got most animated when the BMS Scuderia Italia of Luca Badoer appeared on the screen?
Lauda cautious ahead of qualifyingpublished at 17:26 British Summer Time 6 June 2015
Mercedes non-executive chairman Niki Lauda to BBC Sport: "It is a very difficult race. I am a bit worried because yesterday it rained, Lewis had a crash which did not affect the car and today it is sunshine and cold temperature.
"Lewis did very few laps, Nico did a lot of laps, so I wonder how qualifying will finish. I hope that both Mercedes cars are in the front."
Problems mount for McLarenpublished at 17:23 British Summer Time 6 June 2015

"McLaren have had a very difficult 24 hours. Arriving here with an upgraded engine, aimed at improving reliability and efficiency, Fernando Alonso's developed a problem on Friday and needed to be changed on Saturday morning, meaning he managed only one lap in final practice.
"Jenson Button, half a second off his team-mate and struggling on Friday, had had a smoother run, reliability-wise, until the last 10 minutes of final practice, when his car ground to a halt coming out of Turn Seven. It was a hybrid failure, which required an engine change, and Button will take no part in qualifying as a result.
"Honda, which still has the worst engine in F1, has a long, long way to go to achieve its aim of winning the world title."
Get involved - pit stop blunders #bbcf1published at 17:21 British Summer Time 6 June 2015
We're asking you for memorable pit stop blunders today on the back of Mercedes' problems in Monaco.
Iain: Johnny Herbert in 95 setting off with the rear jack trailing (and rear jack mechanic running!)
Steve Flatman: Jos Verstappen, Germany 1994. Proof you shouldn't mess with the refuelling rig, even if you save a few seconds.
'Hamilton is on the back foot going into qualifying'published at 17:15 British Summer Time 6 June 2015
Andrew Benson
Chief F1 writer
Image source, Getty Images"Canada has cast its spell again, and qualifying has not even started yet. An eventful final practice session saw Nico Rosberg and Lewis Hamilton at either ends of the timing sheets.
"Hamilton had a very messy hour, not managing a representative lap on either type of tyre, making at least two more mistakes to add to the three on Friday. He has clearly not found his rhythm here yet and one can only speculate as to whether this is related to the disappointment of Monaco.
"Hamilton is on the back foot going into qualifying, of that there is no doubt. Can he turn it around on a circuit where he has always been strong, but where last year he lost pole to Rosberg by, yes, an error?"
Button out of qualifyingpublished at 17:12 British Summer Time 6 June 2015
Image source, Getty ImagesBad news to report for Jenson Button fans I'm afraid.
If you were with us earlier you'll know the Briton's McLaren suffered a failure late in FP3 that saw him slow to a halt after turn seven.
McLaren have now tweeted:, external "Button's car suffered ERS-related failure towards the end of FP3. Our engineers are looking at data, but sadly his car won't be ready for quali."

But don't count Hamilton outpublished at 17:06 British Summer Time 6 June 2015
Image source, Getty ImagesIt would, of course, be folly to read too much into the night-and-day gap between the Mercedes drivers in the final practice session.
A gap of 5.8 seconds between Nico Rosberg in first and Lewis Hamilton in 20th is obviously massive, but down only to circumstance, with Hamilton failing to get a clean lap in the gap between two red-flag periods.
Hamilton's fastest lap time was set on the soft tyre after he had to miss the final chicane because he misjudged the entry. Up to that point, he had been about 0.1secs off Rosberg's pace.
And then there are the Ferraris, with their improved engines, to factor in.
This qualifying session could be interesting.
