Barcelona are in talks to sign Ajax fullback Nicolas Tagliafico this week.
The Argentina international is available from Ajax this month and Barca are eager to bring him to Spain.
Sport says Barca have opened talks with Ajax for Tagliafico and have proposed a swap.
The Catalans are willing to include young wing-back Alejandro Balde in exchange.
Ajax would prefer a straight cash sale, though may be willing to take Balde on-loan with a permanent option included for June.
