Sunderland chairman Niall Quinn has confirmed that the Black Cats are keen to sign Preston North End striker David Nugent this summer.
However, the former Republic of Ireland international admits that he is not expecting any developments in the possible transfer until the player returns from the European Under-21 Championships that are currently taking place in Holland.
Quinn said: "The truth is, he's one of a number of players we've made enquiries about.
"We were told - and rightly so, as it turns out - that he's at a very important tournament for his country and, when that tournament is over, Preston have asked us to get back in touch with them.
"That's as far as we had it. We know as well there are a few other clubs involved.
"I can confirm we've made an enquiry and we'll wait and see how the player feels after his tournament, and will the club be willing to sell?
"He's one of a number of enquiries we have made, though.
"To sign a player these days is a difficult, difficult thing. A lot of things have to fall into place and happen."
