Toto Wolff insists George Russell’s Singapore win last time out was “no fluke”. But the Mercedes chief admits he is unsure whether his team can win again in Austin this weekend.

Conditions at the Circuit of the Americas will be very different to the humid night race which Russell won while teenager team-mate Kimi Antonelli was fifth. And Mercedes‘ performance has been inconsistent for much of the year despite Brit Russell’s superb personal displays. But boss Wolff hopes his team can build on back-to-back solid showings in Baku and Singapore to challenge again in Texas.
