Think you know better than a former F1 driver, or do you agree with John's predictions for qualifying later? Make your own here.

Price of a new front wing? Just a couple hundred grand if I've done my calculations correctly based on Tom Clarkson's tweet below.

Team personnel must wince every time a driver brushes against the Wall of Champions in Canada. I know the feeling, I dropped my sandwich yesterday, it was ruined, and I had to buy a new one.

Fuming.

Did Ferrari deliberately engineer the Monaco Grand Prix to ensure Sebastian Vettel beat Kimi Raikkonen? Is Vettel Ferrari’s contractual number one? These questions are buzzing around the paddock still two weeks after the race.

Team boss Maurizio Arrivabene was asked about them on Friday. “No,” he said, they did not have an official number one. “I always said that it’s not that situation in the team. I was very, very clear since the beginning of the season in our rule of engagement, the team it’s above anything. But, until the numbers, they’re not going in one direction or in the other direction - I’m talking about the drivers - no team orders. This is very, very clear. The drivers know about this, they accept it and I think what’s happening in Monaco, I was… let me say I was also a bit laughing when I heard all these comments – because it’s not the reality. The drivers’ championship is their job. They are free to do it, until the numbers are going clearly in one direction or the other. In that case, we apply our rules of engagement – but not now, and not in Monaco.”

Has, like Rubens Barichello and Felipe Massa before him, Kimi Raikkonen joined the number two club at Ferrari?

That certainly looked to be the case after a dodgy strategy call cost him victory in Monaco last-time out. Raikkonen certainly looked pretty miffed on the podium, but do you think it is a role he is pretty happy with, or does he still have the ability to be a world champion again?

Not long until final practice gets under way. You can listen to audio commentary online only from 14:55 BST.

This, thanks to F1.com, is an interesting video showing what actually goes on in a driver briefing.

There were a number of spins on Friday, as there usually are in Canada because of the low-grip, low-abrasion, dirty-because-rarely-used track surface. But Lewis Hamilton said something else was causing it, too. Pirelli’s conservative tyres. “We have the ultra-soft and the super-soft and they are just so hard not providing any grip,” Hamilton said.

“Everyone is spinning off and struggling. The tyres, I don’t have anything positive to say. They are too hard. Rather than the ultra-soft and super-soft it feels like we have the hard and the medium disguised as the ultra-soft and the super-soft.”

The feeling is that Pirelli has met the requirement to produce tyres on which drivers can push flat out for much longer - which the drivers are enjoying, unquestionably, fundamentally by just making them much harder, which they are not. Still, best not be greedy, eh?

It was a bit cloudy yesterday but Montreal is looking mighty fine today. Blue skies ahoy.

Perfect conditions for fans to settle in and watch one hour of practice, which gets under way at 15:00 BST, before qualifying starts at 18:00.

Mercedes or Ferrari? Ferrari or Mercedes? Even the drivers can’t make their minds up.

Sebastian Vettel said: “Mercedes looked good today but I think it will be very, very close, more or less like we all expect it, which is good.” Lewis Hamilton said: “The car feels back to normal but it is still weak in a lot of areas and the Ferrari is still the quickest and with everything I am pushing currently, I can’t beat the Ferrari’s time.”

Kimi Raikkonen topped the second session on Friday by 0.215secs from Hamilton, who headed the first from Vettel by 0.198secs.

This weekend could be a cracker.

Hello! It's qualifying day for the Canadian Grand Prix where once again it is looking like another tight battle between Ferrari and Mercedes for pole position.

Lewis Hamilton topped the timesheet in first practice but the afternoon session belonged to Kimi Raikkonen.

Historically, Hamilton has the edge in qualifying in Montreal having been on pole five times previously. Will he bag pole position number 65 of his career today?

If he does, it will put him level with Ayrton Senna's career total and three behind Michael Schumacher's record of 68.

I've had the Kylie Minogue classic Spinning Around in my head for the best part of 24 hours after watching practice for the Canadian Grand Prix yesterday.

I lost count of the amount of times cars ended up facing the wrong way on the track. In fact, pretty much the only driver to avoid spinning at some point during was Lewis Hamilton but then you'd probably expect that.

No current driver has mastered this circuit as often as Hamilton and that know-how is going to come in very handy as he bids to hunt down Sebastian Vettel in the title race.
