Nico Hulkenberg is confident Force India will see further improvements in Monaco after introducing new developments at the previous race in Spain.
Force India headed to Barcelona with updates which helped Hulkenberg claim his second top-ten result of the season when he brought his VJM05 home in tenth place.
The German, though, reckons the updates are worth more than that and expects Force India will be more competitive in Monaco.
"I think we have taken a good step forward with the developments we made for Spain and they will continue to help us in Monaco," said Hulkenberg.
"We still have work to do to understand and fine-tune them along with the set-up, so that is something the team is working on.
"When you see how close the teams around us are it can really make a difference to find even the smallest gain."
As for Sunday's grand prix, Hulkenberg says he is eagerly anticipating the challenge of racing around the tight, twisty street circuit.
"I enjoy the challenge of Monaco. There's no part of the lap where you can relax for a second - even the main straight is not really a straight.
"I do like street racing in general because you need to grow with the car over the sessions to find the limits. If you get it right you're only a few centimetres from the barrier so there's no margin for error."
