Sergio Perez says Force India must continue its progress and aim for podium positions across the second half of 2015.
Force India's midfield rivals Lotus collected its first 2015 podium in Belgium and Perez believes that his VJM08B will be well-suited to the Italian Grand Prix.
"The race in Belgium was good fun: it's always nice to battle at the front and, even though we didn't manage to get onto the podium, it was good to come away with our best result of the season so far," said Perez, having placed fifth at Spa-Francorchamps.
"Our performance is improving and we are taking the opportunities when they arise. We have seen that we can now fight with nearly everyone and it's important we keep aiming for the podium.
"Monza is a true power track and so we go there confident of being competitive. It’s never easy to overtake and the strategy options are quite limited, and so getting the job done in qualifying is especially important. In the race it’s a case of being flat out all the way and being accurate with your braking points.
"My feeling with the updated car is very good now. Spa was the most comfortable I’ve been this season and it showed in the results. We need to go to Monza and deliver a similar performance."
