Roma legend Giuseppe Giannini is impressed by their summer market work.
Roma are rated among the title favourites this season.
Giannini told TMW: "Definitely yes, to fill the gaps and also they've taken interesting players.
"Edin Dzeko certainly was the icing, a player who can score, but also suitable to put pressure on the opposition.
"Gerson is said to be very good, I want to see him at the Olimpico, I'm curious."
