Neil Warnock is sweating on Aron Gunnarsson’s future – with Besiktas among the clubs looking to land him on a free transfer this summer, according to The Sun.
The Cardiff midfielder’s contract expires at the end of the season and he has attracted interest from foreign clubs.
Besiktas are reportedly amongst four clubs in Turkey looking at snapping up the Iceland captain, who skippered his country to their famous win over England two years ago.
But they face competition from AEK and Olympiacos in Greece, while Dinamo Zagreb in Croatia and American clubs in the MLS have registered interest.
They are willing to match the £40,000-a-week salary Gunnarsson would command in the Premier League but only if Cardiff seal promotion.
And finding a replacement for the central midfielder would give Warnock a massive headache.
The ex-Coventry star was the player of the year last season and has recovered from ankle surgery this term.
Gunnarsson joined Cardiff in 2011 – from the Sky Blues – and has gone on to make 238 league appearances, including 23 in their single Premier League season.
He made 40 appearances in the Championship last term but has been limited to just 15 this time around due to injury.
Gunnarsson has also racked up 77 international caps for Iceland, having been named captain in 2012.
Cardiff City missed two stoppage-time penalties as they lost to Championship leaders Wolves in a dramatic finale, this weekend.
At a packed Cardiff City Stadium, Ruben Neves scored a brilliant second-half free-kick from 25 yards.
After being bundled over in the box, Cardiff’s Gary Madine saw his low penalty saved by John Ruddy.
Moments later, Junior Hoilett blasted a spot-kick against the bar as Wolves extended their lead at the top of the table to nine points.
They need only five points from the final five games of the season to seal a return to the Premier League.
