City manager Pep Guardiola is supposedly keen to shore up his defence ahead of next season, with the right-back spot in particular said to be a concern for the Spaniard.
The Premier League champions have previously been linked with a move for fellow La Blaugrana defender Nelson Semedo, but it appears that Guardiola has turned his attention to another member of Barca's backline.
According to Mundo Deportivo, the Citizens have made contact with the Catalan giants over a deal for Roberto, and Guardiola is keen to reunite with his former player.
However, the report also claims that negotiations are yet to begin between the two clubs, with Roberto's current contract at Barcelona set to run until the summer of 2022.
The 28-year-old has amassed nine goals from 274 outings for the La Liga outfit - including 29 appearances across all competitions during the 2019-20 campaign. body check tags ::
