SAO PAULO – Sebastian Vettel dismissed comments by Max Verstappen as immature and unprofessional on Thursday after the Red Bull driver suggested Ferrari had gained an unfair advantage with their engine.
The Dutch youngster suggested at this month's U.S. Grand Prix that Ferrari's poor performance in Austin was linked to Formula One's governing body closing a potential engine loophole.
The 22-year-old used the word “cheating” in an interview with Dutch television.
“I think everybody is free to say what they want. I don’t think anybody in the team took it personally,” Vettel told reporters at the Brazilian Grand Prix, penultimate race of the season, when asked for a reaction.
“I think it’s not professional and not mature, but I can also see that you are probably interested in me answering back,” added the Ferrari driver.
