Daniel Ricciardo says struggling Red Bull F1 team lost

Last year's Montreal F1 winner Ricciardo was only ninth in qualifying, one place behind team-mate Daniil Kvyat.

"In Q1 and Q2 we did a build-up lap and then a push, but it felt like it was taking too much out of the tyre, so we said by Q3 it should be OK for the first lap," said Ricciardo.

"But it was nowhere, I couldn't get it, and it just wasn't ready.

"We just can't seem to get a sweet spot, which brings out the frustrations.

"The last few races we've had updates, but to be honest they haven't really done anything for us.

"I don't think we really know what we need right now or where to find it.

"We are trying but we are not getting much in return.

"We probably need to take a step back and look somewhere else or try and see if there is something fundamental we are missing.

"Obviously on the power side we know where that is, but on the chassis side there's something there which we can't grab onto which we had last year."

Ricciardo recalled that he had been frustrated after qualifying in Montreal a year ago and still went on to win, though he doubts his Sunday will bring much cheer this time.

"I remember sitting here at this table a year ago, being about as pissed off as I am now, so maybe it means something. I don't know," said Ricciardo, who started sixth in 2014.

"I was furious with qualifying last year, I was filthy with myself."
