Lega, the "far-right" coalition is expected to get between 248 and 268 seats which is below the 316 seats need for majority.
"N. O. No, underlined three times", Salvini told reporters. Obviously, the populist sentiments against European Union control and forced migration were the biggest drivers, but I'm sure some other scapegoats will be found.
Earlier on Monday, its economics chief Claudio Borghi raised the prospect of an alliance with 5-Star - heading for some 32 percent of the vote - which would likely be little interested in further European integration.
By contrast, Berlusconi and his far-right, populist allies were expected to win the majority of seats in the wealthier north, with the centre-left squeezed into a narrow stretch of territory across central Italy, including Tuscany.
Monday's results confirmed the surging of populist, right-wing euroskeptic forces that have swept across Europe and the defeat of the two main political forces that have dominated Italian politics for decades -Forza Italia and the center-left Democrats. The League has overtaken former prime minister Silvio Berlusconi's Forza Italy party as the largest in the coalition.
Analysts say the strong showing by the anti-establishment 5-Star Movement and the rightwing League party means it's less likely the next Italian government will try to make the economy more pro-business.
The League leader's suggestion that the election had produced a clear path to putting him in the premier's office was challenged by the rival 5-Stars, the highest vote-getter of any single party.
Mr Di Maio said: "We are a political force that represents the entire nation".
Matteo Salvini said Monday that the migrant issue was just "one problem" facing Italy and that the League has clear ideas on how to resolve that.

Fernando Alonso: McLaren driver spins off in Formula 1 testing in Barcelona
The Woking-based team had set a target of 100 laps per day at the Circuit de Catalunya after three terrible seasons with Honda . McLaren are still investigating what caused the wheel to come off, as their new era using Renault engines started badly.
This so-called "Universal Wage" has helped the party draw massive support in the underdeveloped south, with pollsters predicting the 5-Star could sweep most first-past-the-post seats in regions below Rome.
Salvini said that for eurosceptics, the results were "a step towards liberation".
Scenarios now include the creation of a more euro-skeptic coalition, which would nearly certainly push for a significant jump in welfare spending and challenge European Union budget restrictions, or swift new elections to try to break the deadlock.
The 5-Star Movement considers itself an internet-based democracy, not a party, and views established political parties as a parasitic caste.
The 5-Stars had a remarkably strong showing in the south, which has always been a stronghold of the center-right and Forza Italia.
Meanwhile senior 5-Star member Riccardo Fraccaro said nobody would be able to govern without his party. It will take weeks of political horse trading to form a government, if at all.
"The Italian election showed that political risk in Europe might not have been top of the agenda for the past year but never went away completely", said John Taylor, a fixed-income money manager at AllianceBernstein. The League didn't even reach 1% there in 2013. The PD's unpopular and reactionary policies paved the way for a degraded, anti-immigrant campaign. The League surged to more than 20% of the vote in Macerata, where a former League candidate shot six African migrants in the election campaign.
Wansleben said both countries have traditionally shaped the European single market and "that must not change with the new government, despite all tendencies in Italy to criticize the EU".
Italian voters delivered a hung parliament on Sunday, flocking to anti-establishment and far-right parties in record numbers and casting the euro zone's third-largest economy into political gridlock, initial results showed.
