However, Marko now tells Sport Bild: "At the next collision, we will have to do a team order, although we are actually against it."
Mercedes team chairman Niki Lauda put the blame on Verstappen at 70%.
"He zig-zagged," the F1 legend told Bild. "That's completely pointless. He does not learn."
Yet Marko insisted that Red Bull has no regrets about signing Dutchman Verstappen, notwithstanding his troubles in 2018.
"We got Max because of his speed and his aggressiveness. Then you have to live with the fact that sometimes sparks fly," he said.
As for whether his relationship with teammate Ricciardo might be broken, Verstappen said no.
"No, no," he told Austrian broadcaster Servus TV. "We talked immediately after the crash and I cannot imagine it will change our good relationship.
"It was not the first time we have fought, and with one exception everything always went smoothly. Our fight before the accident was tough but always fair."
Verstappen said that he is therefore "staying positive" ahead of the Spanish Grand Prix.
"We're getting numerous improvements to the car for Spain so I'm assuming we'll be very competitive there," he said.
Meanwhile, Germany's Suddeutsche newspaper reports that at Baku, official talks between Red Bull and Honda kicked off.
"It was positive," Honda's Masahi Yamamoto is quoted as saying. "This is the beginning of a potential future."
Red Bull are third in the constructors' standings ahead of next weekend's race in Spain.
