Jenson Button reckons rain will provide McLaren with an opportunity in Sunday's Canadian Grand Prix.
Button could manage only fourteenth place in qualifying at the Circuit Gilles Villeneuve.
"We weren’t as competitive as we thought we’d be, and 14th obviously isn’t the place where I want to start, but the good news is that you can overtake around here," he said.
"A race in mixed conditions tomorrow would be good for us."
Sergio Perez believes a red flag towards the end of Q2 cost him a place in the top 10 shootout.
"The red flag at the end of Q2 affected me just as I was about to set a good time. Then, with only two minutes of the session remaining, I didn’t get a run without traffic – as a result, I couldn’t get my tyres up to temperature," he said.
"The fact that some of the others managed to improve was frustrating, but that’s racing; sometimes you get it right, and sometimes you get it wrong. It’s a shame, because I think we had the pace to get into Q3 today."
"Our focus is on the race, and I think we can still score good points tomorrow. It’s not over."
