Barcelona are reportedly considering launching a bid for Liverpool goalkeeper Simon Mignolet.
The Belgium international spent the second half of last season as deputy to Loris Karius, and the arrival of Alisson Becker from Roma has resulted in the stopper being relegated further down the pecking order.
Besiktas have been heavily linked with an approach for the 30-year-old, but Sky Sports News reports that Barcelona may be interested in doing a deal.
Marc-Andre ter Stegen and Jasper Cillessen are currently regarded as the top two goalkeepers at Camp Nou, but the latter could potentially move on before the end of the transfer window.
Besiktas are allegedly ready to spend over £10m on Mignolet, but it is unlikely that Barca would meet that figure unless Cillessen finds a new club.
