Roma president James Pallotta will be in London today for investment talks.
Leggo says Pallotta took in victory over Hellas Verona yesterday before flying to England.
In London, he will be joined by Roma chief Franco Baldini and meet with a US investment fund.
Pallotta is eager to secure fresh capital after a budget of €120m was recently approved by the board.
New contract talks with Kostas Manolas is also on the American's schedule this week.
