London - Toto Wolff has admitted Mercedes' two drivers may continue to struggle with their race starts this year.
Just eight points separate Nico Rosberg from Lewis Hamilton, and the latter has warned that a troublesome clutch system could actually decide the outcome over the final 6 races.
Not an ideal situation
Mercedes team boss Wolff admitted to the German broadcaster Sky: "We have always had starts in the last few races that were not ideal. It's our Achilles heel and we will not be able to solve it this year.
"We have to change the architecture of the clutch for the coming year, because at the moment of course it is a problem for us."

After early clutch trouble in 2016, Wolff had said parent company Daimler would be engaged for help.
But Wolff now says: "We don't know what it (the problem) is - whether it's the design or the construction or whether it's the difficulty for the drivers to operate. There are so many factors involved."
