Former Formula 1 driver Robert Doornbos has said that he thinks his countryman Max Verstappen has a real chance of winning this weekend's Singapore Grand Prix.
Mercedes are still dominating in 2016, but a year ago the great German team mysteriously struggled under the city state's floodlights.
"We believe we now understand why," said team boss Toto Wolff, "but only performance on the racetrack can prove our conclusions right."
The Austrian also predicted that Singapore will "suit the high downforce design philosophy" of the Red Bull team.
Meanwhile, Dr Helmut Marko has revealed that Red Bull are taking car upgrades to Singapore.
Former F1 driver Doornbos said: "Singapore is a good circuit for Red Bull.
"You need a lot of aerodynamic and mechanical grip there and that's what that car is good for. Engine power is also much less important than in Monza."
"Renault is introducing an engine update in Singapore," Doornbos also told Ziggo Sport Totaal, "which means an extra 15 horse power for Max and hopefully a few tenths of time per lap.
"Max loves street circuits and even though he made some mistakes in Monaco, last year in Singapore he drove a crazy race with the famous 'No!' on the radio. Hopefully this year it will be a 'Yes!' on the podium."
Verstappen is sixth in the drivers' rankings going into this weekend's race.
