Niki Lauda believes that his Mercedes team could struggle to retain their dominance at the Russian Grand Prix this weekend.
The Silver Arrows gave won all but three races this year and are set to win their second consecutive constructors championship and drivers’ title.
However, in Singapore Ferrari and Red Bull comfortably defeated Mercedes, and Lauda fears the same could happen this weekend, despite a return to winning ways in Japan.
He said: "Thank God we came out of the Singapore trauma and we are back, that's all I can say.
"It's a big relief we are back where we should be, this is very simple. We are doing what we should do.
"But the championship is not over because my worry is this next race at Sochi has Singapore-type asphalt.
"So it's not done and not that easy. We have to work hard, stay competitive and then we are looking good, but you only look good when it is done."
