Sunderland's defence will need a lot of work ahead of next season. With Carlos Cuellar and Andrea Dossena leaving the club, Phil Bardsley out of contract, Marcos Alonso, Ondrej Celustka and Santiago Vergini's loan deals expiring, doubts over the futures of Valentin Roberge and Modibo Diakite, and John Egan and Louis Laing being released, as it stands only John O'Shea and Wes Brown look certain to be here next season.
With that in mind, Sunderland are hopeful of completing the permanent signing of Vergini but will still need to bring in new faces. The club were linked with a move for Cameroon international Jean-Armel Kana-Biyik recently and have now been linked with a Polish left back.
According to TuttoMercatoWeb, Sunderland are considering making a move for Wisla Krakow defender Gordan Bunoza. 26-year-old Bunoza is out of contract this summer and the player has admitted that's it's time to change club, with Malaga, Livorno, Palermo and FC Basel also linked with the player.
Bunoza, who is a Bosnian international (despite not making an appearance for the international side since 2010), joined Wisla from Croatian side NK Karlovac for an undisclosed fee in July 2010 and has since gone on to make 83 appearances for the Ekstraklasa side.
Despite being 6'5", he is primarily a left back, who can also play in the centre of defence and for all you YouTube scouts out there, you can watch highlights of the player below;
