Mark Webber says both he and Red Bull were given a confidence boost for Monza after a strong showing at Spa-Francorchamps.
Both Spa and Monza have been tipped as circuits Red Bull may struggle on, but they answered such concerns with an emphatic one-two finish last time out in Belgium.
After a poor start, Webber fought back to finish second at Spa, a drive which included a 'sensationally rewarding' pass on the outside of Fernando Alonso heading into Eau Rouge.
The Australian says such the strong showing in Belgium has boosted the team's confidence ahead of Monza, a circuit on which Red Bull are yet to taste victory.
"Spa has given us a little bit of confidence," Webber explained. "We were a bit more competitive in the first and last sector, when traditionally we haven't been.
"This place is different to Spa so we're not coming here thinking we'll be in amazing shape, but Spa gives us confidence - if it was the other way around and Spa was last, we might be more nervous.
"We got beaten on tracks on which we should have won, like Silverstone, so it's been different. Let's hope we are quick here this weekend."
Asked about the pass on Alonso at Spa, Webber said it looked closer on TV than in the car, but admitted it had been incredibly gratifying.
"I had some momentum and I don't know, most people were comfortable on their outlap but I didn't know how Fernando would be," he said.
"I thought we had a chance and had a go. It looked closer on TV than it did in the car.
"We have had sensational battles in the past and that is what it is all about - it was sensationally rewarding."
The Australian also defended Lewis Hamilton, after the Briton came in for criticism following his collision with Kamui Kobayashi during the race.
"He is not that aggressive, he is okay," Webber added. "He has just had a tough run in the last few races."
