Alfa Romeo-Sauber are expecting their C42 car to suit Azerbaijan's Baku City Circuit as the team continues their fight for fourth in the Constructors Standings.
Bottas and Zhou have scored 41 points so far this season, 18 down on the total McLaren duo Daniel Ricciardo and Lando Norris have amassed.
The team have competition from below, however, with Alpine just one point behind in the standings. But they have built a healthy gap between themselves and backmarkers.
It represents a big step forward for the team, who have finished no higher than eighth since returning to the sport in 2019.
Alfa targeting fine margins ahead of Baku
The team's performances on street circuits this season have been mixed but Vasseur believes that the long straights of Baku represent a chance to score big points.
"I do expect our car to suit this track but, then again, our C42 has been performing well in all kinds of circuits so far," said Vasseur, looking ahead to the weekend.
"The objectives remain similar to previous rounds – progress as much as possible with both cars in qualifying and aim to have both in the points come Sunday."
The team boss also said: "We are heading to Baku with the aim to continue our team’s progression this season. We have done really well so far and we can be satisfied with the results we achieved, but we know we will need to keep working hard in every round to get the most out of each weekend.
"We saw in Monaco how the margins are really small: you can go from P6 to P16 in a blink of an eye. This is why we need to be really sharp and make the most of every session, of every lap.
