Toto Wolff urges Mercedes to remember failures as they seek to clinch crown

Following a one-two result in Japan, Mercedes will secure the constructors' title if it scores just three more points than Ferrari at this weekend's Russian Grand Prix. With the Japan result coming after a tough weekend in Singapore, Wolff says he is pleased with the way Mercedes responded but will not let the recovery paper over any cracks.

"Japan was an important weekend for the team," Wolff said. "We had to hit back strongly after Singapore and that objective was achieved on all fronts - in the cockpit and in the garage.

"While we take satisfaction from these successes, however, we do not lose sight of our failures. There are still many obstacles left to overcome this season and we must continue to tackle them with full force."

And Wolff has urged Mercedes not to get complacent as it attempts to wrap up the constructors' title in Sochi.

"We return to Russia with positive memories from last season, when the team sealed the first Constructors' title for Mercedes-Benz with a 1-2 finish," he said.

"A repeat performance in Sochi would be fantastic and this is absolutely the target - but we are under no illusions that it will come easy. The job is not done yet."
