Since Ryan Manning's departure to Southampton in July, Duff has openly talked of his need for a left sided defender.

"He's a left-back, and we need a left-back. So people can put two and two together quite a lot. I think he's a good player," said Duff.

"I've watched quite a lot of him. I watched him when he was a young lad coming through.

"But he's not the only left-back we've been talking to."
