Red Bull Racing's Sebastian Vettel is expecting the Canadian Grand Prix next weekend to be action packed given the Circuit Gilles Villeneuve has a 'high risk potential'.

Vettel suffered his second retirement of the year in Monaco recently and will be looking for better in Montreal, although a lot will depend on just how much progress Renault have made, given its power unit is down on the Mercedes.

"Canada is a very demanding high-speed racing track, which is surrounded by rails and concrete walls. There is definitely a high risk potential, especially in Turn 15, where you will soon get to know the notorious 'Wall of Fame' should you be driving a few centimetres too far to the right," said the four-time F1 World Champion.

"The first danger zone is already at the start. In the very narrow right-left passage, it's all about avoiding contact with the other cars, otherwise there will be a crash."

"It is not uncommon for the safety car to make an appearance at the Canadian Grand Prix," he added.

Team-mate Daniel Ricciardo meanwhile agrees that the Montreal circuit is a real test: "I doubt anyone on the grid lacks motivation, but there's definitely a little extra edge to it at some circuits. They tend to be the ones that demand the most from you and hold real consequences from getting it wrong. Montreal definitely falls into that category," he noted.

"Each of the chicanes (the hairpin too) is an opportunity to make up, or lose, time but the crucial corner is probably the last one: you arrive at top speed so there's a lot to be gained in braking if you get that just right, and then the way you go over the kerbs is worth more time. The flip side is that it's very easy to get wrong and if you do then there's that big wall waiting," he warned.

"It's a clear choice: some guys will play it safe and sacrifice half a tenth to get through there cleanly; others who will take a risk and go flat out trying to find a little bit.

"The nearer you are, the faster you'll go. Give the wall a kiss and you feel pretty good: Kiss it too hard and that's it!" he added.
