After Honda’s tumultuous relationship with McLaren which saw several engine issues arise, Marko has revealed that the Japanese manufacturer had worries that history could repeat itself, this time with Red Bull. But, he remains satisfied that the engine has not been a factor in them failing to compete with Mercedes and Red Bull over this campaign.
"I think they are doing a great job and we have to do it step by step," he insisted.
"I think they are doing the right things and the right job. We believe next year we won't be third."
One concern for Red Bull is the future of Max Verstappen as the Dutchman recently said he was in no hurry to renew his contract with the team after 2020 if they did not prove worthy of delivering the championship.
They have continuously stated their desire to make Verstappen the youngest champion in F1 history, and with 2020 the last year that is possible, Marko admits the pressure is on to deliver.
"I wouldn't say it's crucial. It's the last year where we can make Max the youngest champion in Formula 1 and we have to deliver, yes,” he added.
"But we know that and it's part of our DNA We have to win, yes. It's not crucial, it's a must."
