Williams driver Valtteri Bottas says that the squad is expecting a return to form in Canada this weekend after it suffered a dip in performance in Monaco.
Neither Bottas nor team-mate Felipe Massa managed to collect a top 10 result in Monaco but the Finn posted the sixth fastest time during practice at the Circuit Gilles Villeneuve prior to torrential rain.
"The rain compromised FP2 for everyone but we knew it was coming so we were able to do a little bit of work at the end of FP1 that we would normally do in FP2," said Bottas.
"I did a longer run with higher fuel so we got some information on brake, engine and tyre temperatures, and car balance. Today we were as competitive as we have been on any Friday this year, so we should be looking at least at the same kind of performance as in Barcelona.
"Qualifying can be very close here, even if you get everything right, so we need to make sure we find everything there is to find."
Massa set the eighth fastest time and echoed Bottas' comments.
"We missed a bit of FP2 because of the rain, but before that the car behaved well and I had a good feeling for the balance straight away," he said.
"The grip level from the track was very low, but that’s the same for everybody. This is definitely a better track for us than Monaco. Tomorrow morning will be even more important after the rain today, so we need to understand a lot in FP3 to prepare the car for qualifying."
