Aron Gunnarsson to leave Cardiff City on free transfer this summer?

Cardiff City midfielder Aron Gunnarsson could reportedly leave the club on a free transfer this summer.

The Bluebirds are keen to retain the Iceland international, but a number of clubs in Europe and Major League Soccer are ready to offer him an alternative, according to The Sun.

Gunnarsson, who is out of contract at the end of the season, is said to have attracted interest from four Turkish clubs, including champions Besiktas, as well as teams in Greece, Croatia and the United States.

The central midfielder could earn up to £40,000 a week at Cardiff if they secure promotion to the Premier League, but his suitors are reportedly willing to match those wages to lure him away.

Gunnarsson has made 238 league appearances for the Welsh club since joining them from Coventry City in 2011.
