CHRISTIAN HORNER admits Red Bull must find a solution to their issues quickly after a disappointing Bahrain Grand Prix raised further talk over Max Verstappen’s future.

Red Bull, who have delivered Verstappen the last four drivers’ world championships, appeared well off the pace of McLaren in the opening two races of the season.

A stunning pole and win from the Dutchman in Japan hinted at more potential in the car but he qualified only seventh in Bahrain and endured a miserable race, hampered by two slow pit stops, to finish sixth.
