Barcelona are one of a number of clubs monitoring a future deal for Roma goalkeeper and Brazilian international Alisson, according to reports.
The Brazilian joined the Giallorossi in the summer of 2016 and spent his first season at the club as second choice to Wojciech Szczesny before establishing the position as his own.
Marc-Andre Ter Stegen has established himself as the first-choice goalkeeper at the Camp Nou but according to Gazzetta dello Sport, the Blaugrana may wish to prove him with more competition.
Such a move could lead to the exit of Jasper Cillessen who was signed from Ajax in 2016 but has failed to make a significant impact.
Paris Saint-Germain and Liverpool are also said to be monitoring Alisson.
