"The world of football runs on these rumours, but, yes there have been whispers which I have heard about Rasiak and Sunderland," he told the Sunday Sun.
"Asking if Grzegorz would like to move to the Premiership is like standing outside a chocolate shop with a child and asking them if they would like to go inside.
"Of course he would, though there have been no actual offers for Raziak that I am aware of.
"Anyone interested in buying him would have to speak directly to Derby County.
"Any approach would be to them first, and I have heard nothing yet, apart from a lot of rumours.
"There has been no concrete offer from Sunderland or any other club as yet, so we will have to wait and see."
