The Spaniard has praised the forward as rumors gather that the Brazilian is set to join the Camp Nou club.
News broke on Saturday that the Brazil international had chosen the Blaugrana over Real Madrid, and though Roura has refused to confirm the player will be joining the club, he was quick to lavish praise on the 21-year-old.
"Let things take their course. He's a spectacular player and any club would take him on," he told reporters at a press conference.
Meanwhile, Barca starlet Thiago Alcantara has reportedly caught the eye of Manchester United and Manchester City ahead of the summer transfer window, but Roura refused to speculate on a reported clause in his contract which could be activated by an interested party.
"We decide who plays for sporting reasons," he added. "It's not our job to bear in mind the players' contracts."
A player who will not be renewing his contract is goalkeeper Victor Valdes, who is due to leave the club this summer and Roura acknowledged the reasons behind his departure were "strictly personal".
