The Catalan giants are in need of a cheap option to bulk out their strength in depth at right-back and the Croatian would be an efficient free transfer from Shakhtar
Barcelona are on the verge of completing the signing of Darijo Srna until the end of next season, according to AS.
The Catalan giants are desperate to strengthen in the right-back position but lack the budget to make a big transfer this winter - but Srna could leave Shakhtar Donetsk on a free.
The veteran Croatian has wanted to leave Ukraine for some time and Barca technical secretary Robert Fernandez has maintained contact with him as the club monitored their options for a winter move.
Barca would only be able to afford a more expensive option if they were to sell a player, with Aleix Vidal being the most expendable figure.
However, the Catalan's former youth player's versatility and potential discourages the club from letting him leave.
