"We are about 48 hours away from a deal (on a German-style contract for a programme of government)," Di Maio said, sources said.
"The Gordian knot is the premiership," Di Maio allegedly told members of Five-Star's executive late on Tuesday, according to the sources.
Possible solutions include appointing an "external" individual supported by Five-Star and the far-right League, Di Maio said.
"Otherwise, (League leader) Matteo (Salvini) and I could alternate but that's complicated -- we'd need to agree who would hold the post first," the sources quoted Di Maio as saying.
The third and least likely option would be alternating "external" Prime Ministers -- one chosen by Five-Star and one by the League, the sources citing Di Maio as stating.
Di Maio claimed that the "teamwork" with Salvini was going well despite the odd "tug of war".
"He is much more consistent than the old (Northern) League," Di Maio allegedly said Salvini said on Wednesday that negotiations had entered "the final strait".
Di Maio on Monday asked Italy's president Sergio Mattarella to give the two sides "a few more days" of last-ditch talks aimed at forming a government.
Italy has been in political limbo since the inconclusive March 4 election in which Five-Star emerged as the largest party and the centre-right alliance led by Salvini became the biggest political bloc.
Mattarella must approve Di Maio and Salvini's pick of prime minister and lawmakers must approve their proposed government in a parliamentary vote.
If the Five-Star-League talks on a tie-up fall through, Mattarella will appoint a 'neutral' caretaker cabinet to oversee a re-vote, possibly in the the next few months.
