Mark Webber is not ruling out his chances of a good result this weekend, despite the fact Monza is not expected to particularly suit Red Bull's RB6.
After proving the most consistently competitive car of the season, Red Bull's dominance waned slightly on the long straights of Spa-Francorchamps, where Webber finished second and lost his Championship lead to Lewis Hamilton.
And with the team's Renault engine set to struggle even more at ultra high-speed Monza, boss Christian Horner has predicted a "tough weekend" for Red Bull.
But Webber, 34, said: "I think we can do well again at Monza, although we might have a bit of competition.
"In addition to Ferrari and McLaren, Renault and Force India could be among the contenders for the top positions," he is quoted by Spanish language EFE news agency.
German commentator and former Grand Prix driver Christian Danner told Auto Bild Motorsport that he expects Monza to be "(Lewis) Hamilton country" this weekend.
"Then comes Red Bull and Webber-country," added Danner, referring to the bulk of the remaining five races after Monza.
But Webber achieved pole position two weeks ago at Spa, defying predictions that the RB6 does not have enough engine power for the highest speed circuits.
"We have the same engine as (Renault's) Robert (Kubica) and he was very competitive (in Belgium)," the Australian said.
"We're looking forward to Monza to see how we might go around there," he added.
More Details Emerge On The F1 Of 2013
More details about the shape of radical new regulations for 2013 have continued to emerge.
Earlier, it was reported that most teams have essentially agreed that the field will in future be powered by 1.6 litre, four-cylinder turbo engines, with the cars featuring 80s-style 'ground effect' aerodynamics.
Monday's reports also said drivers will be limited to using just five of the 650 horse power engines in 2013.
The online magazine GPWeek has now revealed some additional details of the new formula.
The publication said the turbo engines will run at about 10,000rpm, and feature an efficient limit on the fuel flow -- culminating in a 'green' formula that some insiders believe might entice manufacturers back onto the grid.
KERS will also play an increasing role in F1's future regulations, with additional heat-recovery technology to likely augment the existing hybrid systems.
Additionally, the cars' sidepods will be moved forwards to increase driver protection, and the size of the wheel rims is expected to increase in future years.
The basis of the 2013 rules are likely to be outlined in more detail after a forthcoming meeting of the World Motor Sport Council.
