The Benfica coach, Quique Flores, sees Pongolle as an ideal addition to the forward-line of the team who have not won a league trophy since 2004/05.
The Eagles have reportedly decided to open their cheque book and spend a total of €10 million for the Frenchman in a deal that is understood to include the move of midfielder Carlos Martins to the Portuguese capital club.
Pongolle's father has said that the 23-year-old is relishing the prospect of returning to one of Europe's top clubs, having spent three seasons at Liverpool.
"We have spoken and for what I can see he will really sign for Benfica," the player's father told Clicanoo. "He had other offers from Spain and France, but he is excited with the idea of going to Benfica."
The striker is expected to fly to Lisbon in the next few days to seal the switch, with reports claiming that he will be officially unveiled by Friday.
