James Matthews: I almost want to see some Red Bull-style outbursts from McLaren. Repeating the same PR soundbites every weekend sounds so defeatist.

Jamie Lee: Eddie Jordan is spot on with McLaren, something needs to change at a once great team! They have the drivers, not the car.

David Dalton: Honda, Ferrari and Renault engines just aren't cutting it, do we need a new engine supplier? Toyota back?

Fernando Alonso on Twitter:, external Jenson Button... Is this a bit better..? Well, probably depends upon how you look at it.

McLaren's Jenson Button talking to BBC Sport's Lee McKenzie: "It's a difficult balance [focusing on reliability and improving the car]. We were weak in both areas this weekend. Hopefully we can solve these issues in two weeks."

"There have to be major changes in the top management of McLaren.

"Ron Dennis has to look at himself and ask 'What is happening on my stewardship?' It was never as bad as this under Martin Whitmarsh."

"Fuel saving, let's get rid of that. It's like battery anxiety in your mobile phone."

Mercedes team boss Toto Wolff on the calls to "lift and coast": "It is a fine margin we have. We want them to compete against each other, so you need to watch the brakes and the fuel consumption and this is the fine line we need to walk on.

"You must not forget that Sebastian had a really messy race. We didn't see the real Ferrari performance today and this is why you have to stay careful and continue to push."

Fernando Alonso speaking to BBC Sport about THAT outburst: "When you are in the middle of a battle, fuel is a low priority and you will time later on. After three or four reminders of fuel, I just said let me race and let me have some fun.

"We are like a different category. When everyone pass you so easy like that, you look like a amateur driver and that is not good. We are not super competitive now, we have many things to do in our case. But hopefully this weekend has given us some lessons

"You need to I believe in this project all the program of developing the car is quite positive. I know it is difficult for the fans but they need to be patient and they need to believe because something good is coming. "

On Fernando Alonso: "He's made his choices in the same way Lewis Hamilton took the decision to leave McLaren for Mercedes when McLaren were a faster team. You can question some of the decisions Fernando has made - he left McLaren one year into a two-year contract because Lewis was fast."

McLaren on Twitter: Cause of retirements: unrelated exhaust issues for both cars. We'll investigate further.

On Fernando Alonso: "I now think he thinks he made a mistake [in joining McLaren]."

...you might just see a dummy flying from Fernando Alonso's McLaren cockpit.

Valtteri Bottas, P3: "I'm really happy for us. It was really good teamwork all weekend. A mistake by Kimi allowed us to make up one position. We really needed this. It really boosts the confidence. We are a top team and we can fight for the podiums."

Nico Rosberg, P2: "I was pushing like mad but I couldn't quite make it. Second place is still okay. It was just a little bit in qualifying - the race pace was good."

Race-winner Lewis Hamilton: "I love Montreal. I love this track, love the city. Fantastic weekend. I didn't feel I had most comfortable balance but I didn't feel under too much pressure. It felt intense, I really enjoyed it. Did I need this? I think so.

"This place is incredible. There are lots of British flags, Canadian flags, Grenada flags and Barbados flags. I won my first race here in 2007 and to be back up here feels very historic for me."

Cora: Started out a good race. Good overtakes. Ended up a fuel saving excercise/procession. Bring back refuelling!

Nicola Fairhurst: So a rodent on the track and Alonso's tantrum were the highlights of the Canadian GP...

Joe Giles: F1 is broken and boring! Just watching out of habit. No excitement, overtaking or even speed.

1986 Canadian GP winner Nigel Mansell: "We need McLaren and Honda, it takes time, hang in there JB, FA - it will get better soon."

That's the 37th win of Lewis Hamiton's career and his fourth at the Gilles Villeneuve Circuit, which was also the scene of his maiden F1 win in 2007.

He is alone in second place on the list of all-time Canadian GP winners, with Michael Schumacher, with seven, the man out in front.
