Speaking to Sky Germany, Helmut Marko discussed Verstappen’s mindset heading into a season where he aims to win his fourth consecutive world title.
“It's business as usual. We are happy that the season is starting again,” he said.
“The tests were very successful, especially the fact that our concept worked so convincingly straight away, that was a great relief.
“Max has gotten even more relaxed and even better, even though it was almost impossible and now we'll see."
Winning is helping the Red Bull camp remain relaxed at the moment, as speculation over Christian Horner’s future continues to swirl around the paddock.
They will need to remain focused on developing their car to remain ahead of the likes of Ferrari and Mercedes throughout the season, if they are to continue their success.
