Haas team principal Guenther Steiner insists Romain Grosjean's lack of points from the first three races is not a worry for the American team.
Grosjean looked set for a top five finish at the opening race in Australia before a cross-threaded wheel nut on both Haas cars resulted in a double retirement for the team. Another opportunity went begging in Bahrain, when Grosjean was knocked out in the first session of qualifying before loose bodywork ruined his chances of a fightback in the race. And at the last round in China, Grosjean finished 17th after an attempted one-stop strategy went wrong and he was forced to make a second change of tyres.
