McLaren's Lewis Hamilton has hit back at Ferrari, calling into question their behaviour in the Formula One spy row.
Hamilton says he is not letting the spy row distract him
"Ferrari are being portrayed as the most innocent team. I do not think that is the case," said the 22-year-old.
"I do not like what Ferrari are putting our team through. I know my team, and we are being been unfairly treated.
"It would be a great feeling to win in Italy this weekend. Beating Ferrari on their home ground is going to be a huge blow to their team."
F1's governing body the FIA is to reconvene its World Motor Sport Council next week to look at new evidence in the row involving McLaren and Ferrari.
And Ferrari said they were "confident that the truth will out" in the hearing.
I've never been rattled in my whole career so I don't want to start that now
But before then, Hamilton is determined to "do his talking on the track" and claim victory at Monza on Sunday.
With five races of the championship left, rookie Hamilton leads team-mate and defending world champion Fernando Alonso by five points in the standings, with Ferrari's Felipe Massa and Kimi Raikkonen in third and fourth places.
In addition to the external pressure of the spying row, within the McLaren camp, relations between Hamilton and Alonso have been extremely fraught this season.
But Hamilton insists he was not letting it get to him. "This is all a new experience for me," he said.
"I am generally a relaxed kind of person and I am not usually rattled by anything or anyone. It is the way I have been brought up.
The spying row has added spice to this season's F1 championship
"I've never been rattled in my whole career so I don't want to start that now."
Hamilton has tasted success at the Monza circuit before, having won the 2006 GP2 championship there, and he said the memory of his rivalry with Nelson Piquet Jr in that competition had proved useful this season.
"That was one of the toughest situations that I had been in," he said.
"I had Nelson breathing down my neck and I had to be in the points to beat him for the title.
"I did that and now I know what it takes to succeed like that. It gets tougher and tougher, but I know that you have just got to go out and do it.
"You just have to do the best job you can."
Meanwhile, McLaren have been fined £25,000 by the FIA for using a gearbox that had not passed a crash test at last month's Hungarian race.
McLaren had informed race director Charlie Whiting on the Thursday before the race in Budapest that they had installed a "lightweight gearbox" in their cars.
McLaren argued that the modifications to the original gearbox were not significant enough to warrant a re-test.
However, stewards said McLaren had "deprived the FIA of the opportunity before the race to consider the changes made and require impact testing to be carried out before use.
"Had such information been imparted in due time the tests could have been satisfactorily completed prior to the Hungarian Grand Prix, such that their use at this event would have been without criticism."
