Christian Horner has backed Sergio Perez to return to form at the Canadian Grand Prix, after the Red Bull team principal warned that the threat of rain might prevent Max Verstappen from dominating yet another race.
Since then, Verstappen has been in a class of his own compared to the rest of the grid, including his own team-mate.
But Horner has now called on Perez to find his form ahead of the race, as he warned that the weather could prevent Red Bull from recording their 100th race win.
Horner: 'Montreal a different challenge'
"Canada is a unique circuit," he said (via Spanish outlet Marca). "It's always great racing there. I think that it's a different challenge. It's a lot of low-speed stuff, a couple of high-speed chicanes.
"But Checo's run well there before, as has Max, and I think that weather can always be a factor there as well.
"We're heading there on 99 victories now, so there's a determination to try and get the century at the next one."
Horner might be correct in stating that Perez has previously done well in Montreal, but you would have to go back more than a decade for his last podium - coming in 2012.
Since then, he has only finished in the points on two occasions, with a gearbox issue forcing Perez to retire after just seven laps in last year's race.
