Qualifying session was special - Alonso
Ferrari president Luca di Montezemolo said it was imperative his team turned their first pole position since 2008 into a win at the Italian Grand Prix.
Fernando Alonso produced a stunning lap to grab pole, while team-mate Felipe Massa qualified third fastest behind 2009 champion Jenson Button's McLaren.
And Di Montezemolo told BBC Sport: "To see Ferrari so competitive in front of our people gives me great satisfaction.
"We have to win - it's easy to say, but we've taken our first important step."
Alonso's pole was Ferrari's first since the 2008 Brazilian Grand Prix and with Button qualifying second fastest, it will be the first race this season that will not feature a Red Bull on the front row.
The Spaniard also gave himself a great chance of reviving his faltering title challenge if he can secure a third win of the season on Sunday.
He fell 41 points behind the drivers' world championship leader Lewis Hamilton when he crashed at the Belgian Grand Prix in the last race.
Hamilton could only qualify in fifth at Monza, while Red Bull's Mark Webber, who is second in the title race, put three torrid practice session behind him to post the fourth quickest time, although both drivers were around half a second off the pace.
Alonso's Italian GP pole-lap
Alonso said: "We need a podium minimum to remain in the fight.
"There is not a big pressure or stress to win the race. But at the same time we know we cannot afford another DNF [did not finish] or bad result, so it is better to be consistent and try to be on the podium. But if we can win the race, great.
"We have a great chance to put a strong result and we see how our opponents finish."
Chief engineer Chris Dyer said first and third on the grid was a "fantastic result" for the two drivers and for Ferrari's chances of winning the constructors' title.
"It has been such a long wait to see one of our cars on pole and there could be no better place to do it than here at our home race.
"We know that usually, one of the F10's strongest attributes is its race pace, therefore tomorrow we must try and consolidate today's achievement," he commented.
"From what we have seen yesterday and today, there are no particular problems in terms of tyre life - maybe the hards struggle a bit more to get up to temperature, but we don't expect to see anything different to usual in terms of strategy."
