22-year-old Roberto broke onto the scene at the Camp Nou in 2010, making his debut in November of that year in the Copa del Rey.
Having been on the scene since making his debut, the midfielder enjoyed his most productive season last year, appearing 17 times in La Liga - and 27 times in all competitions.
However, he has failed to kick on since showing initial promise, and, with only five games to his name this term, Roberto is considered to be on the way out of the club, with Luis Enrique favouring better, younger youth prospects over the 14-capped Spanish Under-21 international.
Manchester United and Tottenham Hotspur have previously been linked with the talented youngster, and a report made earlier this season outlined that he had agreed a new contract with the Catalan club, tying him down with a €30 million release clause.
With his position for the La Liga side under threat, Stoke boss Mark Hughes is looking to take advantage in the January transfer window, and bring further La Masia talent to the Britannia Stadium.
Reports in Spain are indicating that the former Chelsea and Manchester United forward is looking to turn his interest into a concrete bid for the midfielder, having been tracking the youngster since last season.
Along with Bojan - who joined the Premier League side this summer - and Marc Muniesa - who moved to the Potteries in the July 2013 - Roberto could become the third Barcelona academy graduate to be turning out for Hughes side as he looks to bring a new possession, ball-playing style to the team renowned for their long-ball football. All three spent time at La Masia at the same time, and, with Bojan the oldest of the trio at just 24-years-old, it appears as if Hughes is building for a bright future at the Britannia Stadium.
