“We know that some tracks just really don’t suit our car at the moment,” he said.

“Some tracks that are still upcoming won’t really be that good for us, but then also some tracks will be better for us.

Red Bull team boss Horner emphasised Max Verstappen’s ‘demanding’ qualities reflect the team and their goal to remain at the top.

“During the course of a World Championship, sometimes you get into troubled waters,” Horner said according to SpeedWeek.

“And Max is a demanding customer, like everyone else in the team, so he only says what the team feels. Everyone strives for top performance.”
