Marussia driver Jules Bianchi says that the team must start to consistently challenge Sauber, if they are to show that their progress is genuine.
Bianchi scored his and Marussia's maiden points at the Monaco Grand Prix after finishing in ninth place, a result which moves Marussia into ninth in the constructors' championship, ahead of Sauber and Caterham.
An optimistic Bianchi says that battling Sauber, which Marussia has done on occasion in 2014, must be their aim every race.
"I’m very excited for this weekend," he said of the upcoming Canadian Grand Prix. "The car seems so good at the moment that it feels we can go to every race feeling optimistic for a positive outcome.
"It has been such a fantastic week or so since Monaco and it has been nice to celebrate with the team after all the hard work it has taken to get this far. I don’t know if we can get two points again in Canada, but we need to consistently demonstrate that we can keep pace with the Saubers and have a good race, and this I think we can do.
"I think the points success will live with us for a very long time, but equally we have to switch focus to the next races to ensure we keep moving forward, as it is still a long season ahead and the Montreal circuit is by no means a straightforward challenge."
Team principal John Booth played down the prospects of a repeat result.
"It will be interesting to see how well the set-up developments that worked so well for us in Spain and Monaco will translate to the Circuit Gilles Villeneuve," he said. "While we are not expecting to replicate our success in Monaco, we are hopeful that we can further underline our recent performance increment with another strong race for both drivers."
