Manager Sam Allardyce is ken to push through his transfer business as quickly as possible as he looks to improve a squad which narrowly avoided relegation last season.
He is particularly keen to add another centre half to his Sunderland squad to provide competition for Lamine Kone and Younes Kaboul, with John O’Shea expected to provide cover once Wes Brown leaves the club.
He will, like a number of managers this summer, be keeping an eye on Euro 2016 and there is one nation allegedly chief among his thoughts.
That is Austria, with Sunderland scout Gordon Chisholm watching their friendly against Holland on Saturday, the fourth time they have watched the national side.
According to the Sunderland Echo, Allardyce is a big fan of centre halves Hinteregger and Dragovic, both of whom he was linked with while at West Ham.
Dragovic in particular is highly rated and was close to joining Leicester City back in January, but it could be the North East where he ends up this summer.
