Button explains overtaking as 'miscommunication'

McLaren team-mates Lewis Hamilton and Jenson Button are ready to go wheel-to-wheel again as they both chase victory in Sunday's Canadian Grand Prix.
The pair fought for position in the latter stages last time out in Turkey on 30 May as Hamilton re-passed Button to head an all-British one-two.
"We had a good battle," said Button. "And it will be exactly the same here if we both have a good weekend.
"You don't think, I'm going to drive differently as he's my team-mate.'"
Button, who is second in the championship to Red Bull's Mark Webber, added: "It doesn't change anything that you're racing your team-mate - and it shouldn't.
"You race for yourself initially and then you race for your team.
"It's just if you crash with your team-mate there's a bigger issue after the races, as we've seen."
Potential tension between team-mates is still the hot topic in Montreal after Red Bull pair Webber and Sebastian Vettel came together at Istanbul Park, resulting in Webber losing the lead and Vettel crashing out, before Hamilton and Button engaged in a thrillingly close battle for the lead just eight laps later.
Both McLaren drivers had been told to slow down to conserve fuel after the Red Bull clash and so Hamilton was surprised to find himself overtaken by Button after being told by chief engineer Phil Prew that Button would not do so.
Hamilton re-passed Button at the start of the next lap and the 2008 world champion is expecting more on-track tussles with his team-mate.
"We don't have team orders and, of course, we always want to support the team in getting the most points but clearly both drivers want to win," stated Hamilton, who won his first grand prix in Montreal three years ago.
There are no team orders - Hamilton
"So if there is an opportunity [to pass a team-mate] you take it."
McLaren boss Martin Whitmarsh conceded that there had been mistakes communicating exactly what was going on with both their drivers in Turkey.
Hamilton, who is four points behind third-placed Button in the standings, agreed that is an area that needs resolving if McLaren are to build on their 2010 title challenge.
"We have to work on the communication and make sure we are always and understanding one another and getting the point across" Hamilton reflected.
"But what we've also done [since Turkey] is reflect on a great result, our second one-two of the year."
McLaren are confident they can deliver another competitive performance as racing returns to Montreal after a one-year absence.
High-speed is crucial on the man-made island circuit and McLaren expect to have an advantage with their effective f-duct which improves straight-line speed while a lack of high-speed corners will not suit the Red Bulls.
I am hoping we are going to be more on a par with Red Bull this weekend and maybe we can be a little bit closer
"This is a circuit where perhaps there is less opportunity for the advantage of the Red Bull," continued Hamilton.
"There are a couple of corners, Turn Four, Turn Seven, Turn Nine maybe where the Red Bull will be quite strong on those exits but otherwise we should be strong on the straights.
"We have the very long straight here which suits our car more. I am hoping we are going to be more on a par with Red Bull this weekend and maybe we can be a little bit closer."
Button added: "You can't forget about Red Bull but this is a circuit that should work for us quite well, there are long straights, we're very efficient and braking for us is reasonably strong.
"But I don't think we'll be alone out front, Red Bull will be quick, Mercedes will be competitive and you never know about Ferrari."
