David Coulthard believes Lewis Hamilton needs to start clawing back the points he has lost to Max Verstappen from the British Grand Prix.
Hamilton trails Verstappen by 32 points in the Drivers' Championship and has not won a race since the Spanish GP at the beginning of May.
"It's a great start for Red Bull," Coulthard told Channel 4. "The consistency is there, they seem to have the packaging sorted out now, Honda have delivered the power.
"If anybody can pull it back though, Hamilton can. But he needs to start at Silverstone."
Red Bull have won the last five rounds whilst Verstappen is on a hat-trick if victories. Coulthard thinks Red Bull's 2021 machine is an all-rounder and Silverstone will not be easy for Mercedes to beat their title rivals.
"In the past, Silverstone would have been a Mercedes shoe in," said Coulthard. "But you see they have started to struggle in terms of straight line speed relative to McLaren. Nobody can doubt the overall packaging of the Red Bull."
