Dutch defender on trial at Dundee amid growing interest in Jack Hendry from Celtic

The Dark Blues have taken Mart Raternik on trial.

Dundee have moved to cover the potential loss of star defender Jack Hendry by taking Dutchman Mart Raterink on trial.

The Dark Blues have knocked back one bid from Celtic for 22-year-old Hendry but an improved offer is expected before today’s transfer deadline.

It means the former Wigan man could still be on the move and manager Neil McCann is determined that wouldn’t leave him short of options at the back.

He’s brought Achilles FC centre-back Raterink in to have a look at in training.

The 22-year-old is available because of financial problems at his Dutch club and it’s understood, if he moves, no fee would be involved.

He’s in the final six months of his contract and, with the deadline so close, should the Dark Blues want a longer look at him it could be cancelled before tomorrow night.

That means he could still be signed up after the window closes.

Raterink started his career as a youth player with De Graafschap before switching to Achilles two years ago.

Although most of his appearances have been as a central defender, he can also operate in midfield.

Meanwhile, fitness problems at West Ham could rule out a loan deal for striker Toni Martinez.

“I’m not sure Toni is going to be available because he featured for West Ham at the weekend and they’ve been struggling with injuries as well. I wouldn’t expect that to happen,” admitted Neil.
