Wolves chief executive Jez Moxey revealed the club have made a number of “multi-million-pound offers for players” during the January transfer window.

And he is becoming frustrated at drawing a blank with these bids with the window due to close at the beginning of next week.

Wolves boss Mick McCarthy has so far signed the Charleroi duo of Adlene Guedioura and Geoffrey Mujangi Bia on loan with a view to permanent deals being completed in the summer.

Hull midfielder Stephen Hunt remains a top target for McCarthy whose side visit the Tigers for a crunch Barclays Premier League relegation clash at the weekend.

Moxey said: “We have been trying to improve our squad with the capture of experienced top-flight players but these efforts are proving frustratingly difficult.

“At present clubs are just not prepared to sell players who fit that bill.

“The main obstacle for us has not been the lack of money available for players.

“We have made a number of multi-million-pound offers for players which have been knocked back. We have also been involved in discussions with a club about a deal which would potentially have seen us break our transfer record. Finance is not the main issue.”

Moxey also stressed Wolves would not be held to ransom when pursuing potential targets.

l Mick McCarthy has hailed striker Kevin Doyle after asking him to act as a lone striker in their 0-0 draw with Liverpool.

It took the Molineux men to the 20 point mark for the season in their battle to stay in the Barclays Premier League – and kept them out of the relegation zone.

McCarthy felt his side were well worth their point at Molineux thanks to a revamped 4-5-1 formation.

He said: “If you see a better performance from a centre-forward than Doyle showed I would like to see it.

“If he had just managed a goal, it would have been one of the best all-round performances. He is physically strong enough to play that role.

“We changed the system and I don’t think our keeper had a save to make. I don’t think we were troubled.”
