Romain Grosjean believes that Haas can benefit from the raft of changes at Toro Rosso, and overhaul the Faenza-based team in the championship.
Toro Rosso battled with Williams for fifth in the standings earlier in the campaign but the Mercedes-powered outfit has pulled clear, with Toro Rosso dragged into a scrap for sixth spot.
Toro Rosso has scored just once in four races amid a revision of its driver line-up, with Renault-bound Carlos Sainz Jr. and the axed Daniil Kvyat replaced by Pierre Gasly and Brendon Hartley.
Toro Rosso now holds a slender five-point advantage over Renault, with Haas in turn just one point behind, as it chases an improvement on its 2016 placing.
“I think out of those teams, Renault is the faster one,” Grosjean said, analysing the gaggle of teams.
“They’ve got a really good car through to the end of the season. They’ve had a bit more of a difficult time in the races, which has allowed us to close the gap and keep them in sight.
“Toro Rosso is the one we can try to go for. They’re not performing better than we are, and they’ve got less experience amongst their drivers, so that should help us.
“We’re going to do everything we can to get those positions because it’s very important for the team.”
Haas team-mate Kevin Magnussen also believes the operation can emerge on top of the three-way tussle, but is wary that the outfit has to “get everything out of it” in order to win the scrap.
“It’s only one point now to Renault for seventh in the Constructors’ Championship, and it’s only six points to Toro Rosso,” said Magnussen.
“It’s extremely close and anything can happen in these last two races. We just need to be on top of everything and get everything out of it that we can.
“It’s not going to be easy. Those teams are doing well and they’re tough competitors.”
