Despite the financial troubles faced by the Vijay Mallya owned Kingfisher Airlines, Force India has performed strongly on track and has achieved its highest ever points haul (currently 89) and lies seventh in the constructors' standings.
Hulkenberg, who has also recorded a fourth place finish this season, echoed his teammate's confidence in the team establishing itself as a strong mid-field outfit.
"It makes me optimistic for the weekend," said Hulkenberg. "I think last year was a difficult one for us but we are in much better shape now."
The long-term future of both drivers has been a subject of much speculation following the movement in the driver market due to Lewis Hamilton's switch to Mercedes.
Hulkenberg, however, refused to comment on the rumours of his move to Sauber while Di Resta stated that it is not the team's policy to discuss driver contracts.
