Derby boss Nigel Clough has confirmed that he is eager to sign former Leicester defender Patrick Kisnorbo.
The 28-year-old Australia international is available on a free transfer after he was deemed surplus to requirements at the Walkers Stadium, and he is said to be attracting interest from Crystal Palace.
However, Kisnorbo is currently on trial at Pride Park and, after playing a significant part in The Rams' pre-season friendly at Burton Albion on Saturday, Clough is set to open talks.
"We were very pleased with what we saw from Patrick for around an hour," he said.
"It is well documented that centre-half is a position we are looking to improve and he may well be an improvement on what we have got.
"He has got Championship experience and although he is not 6ft 3in or 6ft 4in, he competes well and he can play full-back as well so it covers us in that position.
"We will sit down and have a chat with him."
Clough will not follow up his interest in fellow trialist Mark Fotheringham, however.
The 25-year-old former Norwich midfielder also featured in the Burton match but, despite his best efforts, failed to earn a deal.
"I've had a chat with Mark and the problem is we've got three good players in the middle in Paul Green, Robbie Savage and Stephen Pearson, and all of them are on contract," he said.
"We probably cannot pursue anything with Mark, but for a week I've never seen a trialist come in and work as hard as he has."
