Red Bull team principal Christian Horner is very confident that Max Verstappen will win the Brazilian Grand Prix.

The Dutchman was trumped by Valtteri Bottas in the sprint race on Saturday and had to leave pole position to the Finn.

"Mercedes took the gamble with Valtteri to start on the soft tire and it worked out really well. We started on medium and Max had some gear changes early in the race," Horner told

Sky Sports

.

"I don't think there was more in it. In the end we still managed to gain two points. We like to take that with us and tomorrow it will be a completely different race, especially because it promises to be much warmer."

Red Bull is generally strong on circuits where the temperature is high, while Mercedes regularly struggles with cooling problems.

Thanks to his second place, World Cup leader Verstappen was two points clear of Lewis Hamilton, who finished fifth after a spectacular catch-up race.

Verstappen is now 21 points ahead of his title rival (314.5 to 293.5 points).

Horner has doubts about Mercedes rear wing

Hamilton was removed from qualifying for the sprint race on Friday due to a DRS opening that was too large and as a result had to start at the back at Interlagos.

Horner doesn't think Mercedes' high top speed was the result alone and questioned - not for the first time this season - the legality of the full rear wing.

"In Turkey we already started to see it and in Mexico Mercedes was suddenly 14 kilometers per hour faster on the straight than we were," continued Horner.

"There is something about that car that makes them reach such high speeds. According to our calculations, those speeds are not possible at all. We are trying to understand how that is possible."

Behind Bottas and Verstappen, Carlos Sainz finished in third place and Sergio Pérez finished fourth.

The Brazilian Grand Prix starts on Sunday at 6 p.m. Dutch time.
