Red Bull team adviser Helmut Marko has admitted that “the concern is great” about Max Verstappen ’s future with the Formula One team due to its current car struggles.

Max Verstappen has dismissed concerns that he might consider leaving Red Bull, after last weekend’s Bahrain Grand Prix proved to be a turbulent day for the team.

Max Verstappen refused to entertain speculation about his F1 future on Thursday, insisting he is “just focused on driving.” The four-time F1 world champion has only tasted victory once so far this season, in Japan, and finished a disappointing sixth last weekend in Bahrain.
