Helmut Marko says there are serious concerns that Max Verstappen could leave Red Bull at the end of the season if the team does not improve its performance.

Verstappen finished sixth at the Bahrain Grand Prix after overtaking Pierre Gasly on the final lap of the race, but was over half a minute behind race-winner Oscar Piastri despite a safety car neutralizing the race with just 24 laps to go. After Verstappen struggled so heavily with tire degradation, balance issues and braking problems, Marko admitted solutions need to be found quickly.
