F1 2009 world champion Jenson Button has said the Canadian Grand Prix will be all about tyre management and that the start tomorrow at the Circuit Gilles Villeneuve could be 'interesting'.

Button will line-up fifth on the grid for the eighth round on the F1 2010 schedule, and reckons Red Bull Racing's Mark Webber and Sebastian Vettel, who will start on the harder of the two Bridgestone tyres in second and third, could get 'frustrated' if they can't get by pole man, Lewis Hamilton.

Button, like Hamilton, will start on the option (softer) tyre - as will Fernando Alonso in fifth and most of the other runners in the top ten - and the Englishman thinks the different strategies will spice up proceedings.

"It's good to see that some teams were running different tyres in Q3 - that's the first time that's happened this year," Jenson reflected. "Red Bull set their fastest laps on Primes, so it's going to be an interesting start to the race, seeing if they can overtake.

"The Prime is the quicker tyre, but they're going to have to change to the Option at some point during the race. And if they get stuck behind Lewis in the early laps, then I'm sure they're going to get frustrated.

"I think it's going to be a good race - both fascinating and fun - and strategy will be very important: it will be all about tyre management, so going flat-out every lap might not be the quickest way to get to the end of the race in the shortest possible time."

Button's best lap in Q3 was a 1 minute 15.520 seconds, that left him four tenths off Hamilton and he conceded Lewis' lap was special.

"I was happy with my Q3 lap, but I couldn't touch Lewis - it was a phenomenal lap from him. He's qualified on pole every time he's been here, so he's obviously a specialist around this place," Button continued. "Fifth place isn't where I'd ideally like to be, but I gave it everything and I couldn't have gone any quicker."

McLaren boss Martin Whitmarsh meanwhile was happy to see his drivers' line-up first and fifth: "Today we saw a stunning and dramatic lap from Lewis to snatch pole position in the last seconds of qualifying. He loves this circuit - he scored his first ever grand prix pole position and his first ever grand prix victory here in 2007, of course - and, having won in Turkey two weeks ago, he's very motivated to continue his winning run here in Canada," Whitmarsh noted.

"He did his time on the Option tyre, and will therefore start on it tomorrow. Clearly, it's less durable than the Prime, but you have to use it some time and we think we've got a strong strategy for the race.

"Jenson did a very solid job, too, securing fifth place on tomorrow's grid, and is also well placed to score plenty of points tomorrow. He's consistently shown himself to be an extremely fast and combative driver in race conditions - and, all things considered, we're very happy with how things are shaping up for tomorrow."
