Mercedes on red alert as Wolff backs Hamilton

Shanghai : Mercedes team boss Toto Wolff has backed Lewis Hamilton to exact swift revenge at Sunday's Chinese Grand Prix after a chastening defeat in Formula One's season opener in Australia.

Sebastian Vettel's comprehensive victory for Ferrari has put Mercedes on red alert ahead of the Shanghai race weekend but Wolff insists Hamilton has the steel to strike right back after finishing second in Melbourne.

"Lewis is the best Lewis that I've seen in the last four years -- both on and off the track," said the Austrian. "He's become a pillar of this team and he proved that in Melbourne. 

"You need to be careful to manage your own expectations. 

"If you think you are going to cruise to victory in the future, based on a track record of success, you'll be proven wrong very quickly. You need to put the finger in the wound, identify your weaknesses and then respond."

Hamilton, who busied himself with a spot of scuba diving this week, has previously won four times in China but the triple world champion will be mindful of his sluggish start to the 2016 campaign.

Former team-mate Nico Rosberg reeled off four straight victories before the Briton finally hit his stride in Monaco in the sixth race of the year.

Rosberg's hot start helped the German pip Hamilton to the world title before sensationally walking away from the sport.

Valtteri Bottas replaced Rosberg and the Finnish driver took third in Australia on his debut for the Silver Arrows.

But Ferrari have shown impressive early pace, with 2007 champion Kimi Raikkonen taking fourth and all the signs point to another tight battle between the two top teams in China.

A buzzing Vettel, who romped to four successive world titles with Red Bull from 2010 to 2013, will fancy his chances of further getting under Hamilton's skin.
