For someone regarded as one of the best footballers ever, Diego Maradona's career is littered with regrets and what ifs, and his disappointing and chaotic two-year stay at Barcelona ranks particularly high among them.
Maradona signed for Barcelona in 1982 after a protracted transfer from Boca Juniors, who visit the Camp Nou on Wednesday as Barca's opponents for the traditional Trofeo Joan Gamper, the team's final preseason friendly.
A statue of Maradona greets visitors at Boca's museum and it is hard to walk around the surrounding area of La Bombonera without seeing his image on murals, even though he only won one league title with the Buenos Aires giants.
