Barcelona management have concerns Jasper Cillessen could yet kick up a fuss in January over his lack of action this season.
The Holland goalkeeper spoke openly about leaving Barca last summer, though ultimately chose not to push for a departure.
However, Mundo Deportivo says management recognise Cillessen could yet choose to leave over the New Year given his situation hasn't changed.
As such, Barca have drawn up shortlist of potential replacements.
Koen Casteels (Wolfsburg), Jeroen Zoet (PSV), Timo Horn (Koln) and Jiri Pavlenka (Werder Bremen) are all under consideration.
