"If things go according to the plan we have prepared, we will see an improvement in two years," the 59-year-old former army chief told Sky News Arabia in an interview yesterday.
Egypt's "problems will be over in two years", he added.
Sisi, who deposed Islamist leader Mohammed Morsi last July after mass protests against Egypt's first democratically elected president's rule, is expected to sweep the May 26-27 election.
"I won't wait for the army (to intervene) ... The army acts according to the people's will," Sisi added.

Since Morsi's overthrow, more than 1,400 people have been killed and thousands of members of Muslim Brotherhood detained by authorities, who have designated the Islamist movement a terrorist group.
Analysts say Sisi is expected to easily win the election. The only other candidate is leftist politician Hamdeen Sabahi, who came third in the 2012 election won by Morsi.
Sisi is popular among Egyptians who supported the army's decision to remove Morsi from power. His supporters see him as the kind of strongman needed to end the turmoil dogging Egypt since a popular uprising ended Mubarak's three decades of one-man rule in 2011.
Egypt has been rocked by more than three years of political turmoil that toppled two presidents after massive street protests, a deadly crackdown on Islamist protesters and a spate of militant attacks that has left the country deeply polarised and the economy in a shambles.
