Grosjean concerned by race-day problems for Haas

Haas F1 driver Romain Grosjean is yet to score a point this season, and the Frenchman has revealed he is concerned by some of the issues that have impacted the American outfit on race-day.

Grosjean is pointless in 2019; this is despite qualifying in the top 10 in all three races. Haas have really shone on Saturdays - with it being qualifying - but when it comes to race-day (Sunday), they tend to go backwards rather than forwards.

"The car is fast in qualifying and we know it, so that's how we've managed to go through to Q3," Grosjean said. "That's why we've made it into the top 10 each Saturday this season.

"But when we go into the race, we're losing the grip and things become a bit more complicated. We have good grip in qualifying. On new tyres, the car is amazing."

Haas are now investigating why the grip for the races is not the same as it is in qualifying, according to Grosjean who believes the tyres are at te heart of the problem.

"The grip is going," Grosjean added. "That's the problem we're facing at the moment. It's probably coming from the way we use the tyres. We haven't managed to get on top of it yet. That's our number one priority for the next few races."
