Mercedes boss Toto Wolff says he team needs to be wary of how quickly Ferrari can come back in to the title race.
Sebastian Vettel won the Hungarian Grand Prix - his second win of the season - as Lewis Hamilton finished sixth and Nico Rosberg eighth in a dramatic race in Budapest. With the teams now taking stock during the mid-season break, Vettel is just 21 points behind Rosberg in the standings, while Hamilton enjoys a similar margin at the top of the championship.
Wolff says Hungary highlights how quickly the situation can change and calls on Mercedes to be alert as it defends its advantage in Belgium.
"You just need to be careful," Wolff said. "We’re just 42 points ahead in the Drivers’ World Championship and you can see how quickly it goes. You have a bad day, two cars not scoring good points and ‘boom’ you go backwards.
"But that is a mentality we’re having anyway of always being a bit sceptical about how we are doing."
In terms of the constructors' championship, Mercedes currently enjoys a lead of 137 points over Ferrari as it chases back-to-back titles.
