Red Bull advisor Helmut Marko has explained that Max Verstappen had speed to spare during the Azerbaijan GP.
Verstappen jumped Lewis Hamilton in the pitstop phase to take the lead and was on course for his third win of the season until his tyre dramatically blew out with five laps to go.
"We controlled the race with confidence, Max at the front with one fastest lap after the other," Marko told ORF.
"He was not at the limit, not at his maximum speed, and the tyre management was optimal."
Marko reiterated comments from Christian Horner and Verstappen that there were no indications of a tyre blowout but he was relieved to win the race with Sergio Perez who nearly failed to finish the race.
“There were no signs of a vibration or too high temperatures," said Marko "Suddenly it was bam, a crash and your heart fell in your pants.
"Thank God there was still the restart was. It was a bit of a butt-pinching with Sergio Perez, because he had some minor problems.
"The longer the race went on, the bigger those problems got. In the end, it all ended well. It was just a shame that Verstappen retired because we could have drastically expanded our lead in the championship."
