Lewis Hamilton is still better than Max Verstappen, according to the Red Bull driver's boss Dr Helmut Marko.
"Max may already be the fastest," Marko told Germany's motorsport-total.com.
"But as a package, Hamilton is still the best," he added, referring to the Mercedes driver and reigning six-time world champion.
"He has an incredible basic speed and obviously much more experience than Max, and that is a huge advantage.
"Naturally, it's better to drive a car that gives you an easier life, and that's what Red Bull wants to change in 2020," Marko added.
