"If one or more political forces is credibly backing (my) agenda or even has a better one, I'd evaluate the offer," Monti said during a news conference.
"To those forces who demonstrate convincing and credible adherence to the Monti agenda, I am ready to give my appreciation, encouragement, and if requested, leadership, and I am ready to assume, one day, if the circumstances require it, the responsibility that would be entrusted to me by Parliament."
Monti ruled out heading any ticket himself, saying "I have no sympathy for `personal' parties."
Italy is struggling to shore up its finances and emerge from recession, a challenge made harder by its volatile politics, which saw dozens of governments over the years that let tax evasion spread, avoided unpopular reforms like raising the retirement age, and allowed public spending to balloon.
Monti was appointed in November 2011 to head a non-elected government with the goal of saving Italy from a Greece-style debt debacle after financial markets lost faith in his populist predecessor, Berlusconi.
Berlusconi triggered Monti's resignation last week, a few months ahead of the term's end, when he yanked his Freedom Party's support in Parliament for the government. Parliament was then sent packing last week by Italy's president, and elections scheduled for Feb. 24-25.
Monti's announcement Sunday pleased some parties but irked others.
`'Yet again, Monti shows himself to be arrogant and (Pontius) Pilate-like," said Antonio Borghesi, a leader of the small center-left party that refused to back him during Monti's 13 months at the head of a non-elected government. "He won't directly commit himself, but he doesn't rule out that his name be used by others who share his agenda and he gives his willingness, if asked, to again leader the country."
The tiny centrist Italy Future party, meanwhile, hailed Monti as a `'great political leader and international statesman," and said in a statement: "We reiterate our willingness to back with pride the agenda of Premier Monti."
Monti said he was spurning Berlusconi's offer not to run himself but instead support a center-right ticket headed by Monti. The premier expressed bewilderment that Berlusconi alternated sharp condemnation of the government's economic policies, with the seemingly contradictory offer to back another Monti-led government.
"Yesterday, we read that he assessed the work of the (Monti) government to be a complete disaster. A few days earlier I read flattering things," Monti said of his predecessor. The logic of Berlusconi's positions "escapes me" Monti said, drawing chuckles.
Berlusconi has said he would try for a fourth term as premier if Monti doesn't run, even though he continues to face several legal and sex-related scandals.
Monti praised Parliament for backing his government's recipe of spending cuts, new taxes and pension reform, which he said saved Italy from the debt crisis.
"Italians as citizens can hold their heads up high in Europe," Monti said, noting Italy had avoided the bailouts that Greece, Portugal, Ireland and Cyprus have had to take.
"We have always been convinced that Italy had, in itself, the resources" to succeed, Monti said. "And that's what happened."
Italy's President Giorgio Napolitano dissolved Parliament after Monti resigned Friday following approval of the country's national budget law. Monti noted that as a senator-for-life, he remains in Parliament and thus doesn't need to run for a seat in the legislature.
Voter opinion polls indicate a centrist ticket backing Monti would take about 15 percent of the vote, meaning any government headed by him would need support from either of Italy's two largest political groupings: the center-right, led by Berlusconi, or the center-left, led by Pier Luigi Bersani.
After Monti's announcement Sunday, Bersani vowed to "preserve" the premier's anti-crisis efforts. But Bersani, whose forces lead in opinion polls, expressed equal determination to avoid what Monti calls the "strange majority" of center-left, centrists, and center-right in Parliament.
That grouping until earlier this month largely set aside differences to back reforms such as raising the retirement age.
Bersani's forces turned out to be Monti's staunchest proponent this past year. By declining to directly campaign for February's balloting, Monti avoids a direct clash with him. On Sunday, Monti would only would say that Bersani is a highly "legitimate candidate for premier of a coalition."
In an interview on state TV later Sunday, Monti declined to say if he thought his agenda would get more backing from Bersani's or from Berlusconi's forces.
Some had speculated that Monti had his sights set on the Italian presidency, since Napolitano's term ends this spring. But Monti ruled that out at the news conference.
