Sainz was unlucky in Canada, as he spent the majority of the race inside the top 10, but a determined Lance Stroll (on fresher tyres, also) and a superb move from Daniil Kvyat ensured the Spaniard could only manage P11 in Montreal.
That was the first time since China that Sainz had failed to score a point in a race after an impressive start to the season with his new team McLaren. Sainz is hopeful his team won't be getting complacent in France, though.
"We are now a third of the way through the season and, as expected, the midfield is getting tighter," Sainz explained. "Every race is an opportunity we must take.
"We recently saw how we are able to score at tracks that really didn't suit us much and, at the same time, how small details can leave you out of the points. That means there is no margin whatsoever to sit back and relax, so we are coming to France fully focussed and wanting to push hard again.
"I'm looking forward to heading back to the south of France this weekend. The track might still be new to modern Formula 1, but I have had some great races there before in the junior formulae.
"It's a lovely part of the world and I really hope we can put on a good show for all the fans."
