Mercedes boss Toto Wolff believes every team poses a "potential threat" in the 2019 season, as the Silver Arrows look to continue its dominance of the sport.
Lewis Hamilton won his fifth world championship in 2018 and helped Mercedes clinch its fifth constructors' championship on the bounce.
Mercedes launched their new 2019 car, the AMG F1 W10 EQ Power+, and their boss is not taking anything for granted as we approach the new Formula 1 season.
"Every team can have a shot at the title and we're seeing all of them as a potential threat," Wolff said, as quoted by BBC Sport.
"There is absolutely no feeling of entitlement to be at the front. The regulations have changed quite substantially. We have to start from scratch. We need to prove ourselves again - against our own expectations and against our competitors."
With just a month to the new season starts in Australia, world champion Hamilton, who will be driving alongside Valtteri Bottas for a third season, wants to achieve even more than he already has with the German side.
"2018 was a great year, but I feel like 2019 can be even better," the Brit said. "I want to achieve more. I want to continue to keep pushing."
