Despite Max Verstappen's strong start to the season, Red Bull Racing chief executive Helmut Marko is not completely satisfied.
The Austrian even calls it painful that the lead in the World Cup position over Lewis Hamilton is only four points.
"It just hurts. We are the fastest combination of car plus driver," Marko told
Auto, Motor und Sport on
"But we are only four points ahead."
"That doesn't reflect our strength. We should have been 15 points ahead by now. But with the luck that Mercedes has, you have to be happy with every point you can take."
On Sunday, Verstappen was on his way to victory in the Azerbaijan Grand Prix, until he suffered a blowout in the final phase.
Because his competitor Lewis Hamilton slid off the track at the restart, the damage in the World Cup battle was limited.

Marko thinks Red Bull package is faster than Mercedes
The race in Baku was won by Verstappen's teammate Sergio Pérez.
As a result, Red Bull has won this season's two street races (Monaco and Azerbaijan).
The third street race in Singapore disappeared from the calendar due to corona measures.
"In Monaco and Baku we indeed had the fastest car, but also on other circuits," says Marko.
"Maybe not just in Barcelona, but that was due to tire wear. I think in general we have a faster package than Mercedes."
"In Azerbaijan, Verstappen could have raced even faster if he had wanted to," says Marko, who disputes that the flat tire could have been caused by Verstappen asking too much of his car.
"We just checked the race."
The Formula 1 season will continue on June 20 with the French GP.
