Roma chief exec Guido Fienga has welcomed new signing Pedro.
The former Chelsea attacker has signed a three-year contract and arrives on a free transfer.
“It's a privilege for us to be able to welcome a player of Pedro's quality to the Roma family," Fienga told the club's official website.
“The hope we have, for both him and for us, is that he can continue to add to his extraordinary list of achievements with AS Roma."
Pedro is the first signing of the summer but is unlikely to play when the season starts on September 19, as he is currently recovering from a shoulder injury.
