Montreal - Sebastian Vettel says Ferrari has a few tricks up its sleeve for this weekend's Canadian Grand Prix and the team will need to conjure up something special if it is to end Mercedes' magical run.
Six races into the season, Vettel is not ready to wave the white flag and concede the title to Mercedes, which has racked up six straight wins, five in one-two formation, but the German admitted on Thursday that the battle had reached a critical juncture.
"The next races will be really crucial for us to try and get back to the front and give a much harder time to Mercedes," said Vettel, who finished second in Monaco last month for the team's best result so far this season.
"It will be crucial to do it rather sooner than later but at the moment I am not too fussed, I am not looking at OK this is the date.
"Clearly we are behind, clearly there is a big margin between Mercedes and the rest and we have to lose that gap and get ahead otherwise it will be difficult to turn around.
