Lewis Hamilton will start tomorrow’s Canadian Grand Prix (start: 20.00) as favourite for another win but Formula One’s triple world champion remains wary of potential potholes ahead.

The Mercedes driver has won four times at the Circuit Gilles Villeneuve, including from pole last year, while team-mate and championship leader Nico Rosberg has never tasted victory in Montreal.

Hamilton’s first win of the campaign in Monaco two weeks ago ended a barren run marked by bad luck and closed the gap to the German to 24 points.

Another victory for the Briton, and a blank for Rosberg, would see Hamilton riding a wave to the top of the standings.

“This has been a naturally good track for me so hopefully I should be able to capitalise on that,” Hamilton told reporters.

“But the weather is all over the place and I’ve had bad races here as well.

“I feel positive coming here but I am conscious how the season has gone so far. I am not arriving all excited thinking everything is going great again just because we have had one win.

“There are potholes we could easily manoeuvre but I’m conscious we could fall down them.”

Hamilton’s first win at the Canadian track came in his rookie season in 2007 but there have been some lows.

In 2008 he collided with Ferrari’s Kimi Raikkonen in the pitlane and retired, and in 2011 he collided with then-McLaren team-mate Jenson Button while trying to overtake and went into the wall.

He admitted his head was ‘banging’ after celebrating a much-needed win in Monaco, where Rosberg finished seventh.

“I arrived at the last race 43 points behind and I arrive now 24 behind so it just shows the goalposts are moving,” Hamilton noted.

“With 15 races still left, anything can happen.”
