Rangers boss Stuart McCall says he feels sorry for Gael Bigirimana, but admits he should never have been signed.
Chris Gunter will stay at Reading, after the club took up the option to extend his deal by another year.
Leeds chief Brian McDermott admitted earlier this week he tried to land a mystery winger on deadline day, only to see his price-tag end his interest in the player.
Clark has now confirmed he spoke to McDermott about Burke and he insists the Scotland international is happy to stay at St Andrew's, despite the interest from Leeds.
"I had a conversation with Brian on Sunday. He basically asked about Chris," said Clark.
"They (Leeds) said they were willing to do that deal, but thankfully Brian didn't come back and pursue it.
"Chris is 100 per cent happy and he's enjoying it here. He's never indicated to me that he has ever wanted to leave."
