"I don't see any great possibility of Narendra Modi becoming the Prime Minister. Even if he gets more seats than us, he would not get support of the regional parties," Chavan said at a press conference here.
"As the other alternative, Congress and third front can form the government. We will try to form a secular government," he added.
The senior Congress leader, who has stoked a controversy by stating in a newspaper interview that regional parties should not be allowed to contest the Lok Sabha elections, said his only rationale was it could bring a stable government.
"It (allowing regional parties to contest Lok Sabha polls) is likely to create a political instability. It is something to discuss. Neither I nor the Congress alone can do it (ban regional parties from contesting polls)," he said.
Sharad Pawar-led NCP, alliance partner of Congress in the state, has opposed Chavan's stand.
