JOHN HARTSON has slammed Josip Juranovic's agent amid constant speculation linking the defender with a move away from Celtic.

Chelsea have been quoted with an interest in the Croatian international this week, while other European clubs have also been linked.

Hartson has hit out at Juranovic's agent saying the representative is "causing anarchy" by linking his player to clubs.

The Celtic hero told Sky Sports: "That will happen when you play for a global club. Celtic, Rangers; if your performances are very, very good then clubs are going to come calling.

"But listen, Josip Juranovic has been at the club for two minutes and his agent is linking him with clubs. He has done really well, he has got in the team.

"He is a really effective player when he gets forward in the box, but his agent shouldn't be touting him about like this.

"His move is going to happen, that's football. But stay at Celtic, play football, you have become a champion, you are in the side and your manager really likes you.

"These agents cause anarchy because they just want to fill their own pockets. Three, four years down the line you may get your move, but at this moment in time he has been at the club for five minutes doing very, very well.

"I'm sure Ange won't want to lose him. He has been outstanding."
