Naughton has no confirmed interest
His Gaffer Kevin Blackwell said: "As far as I am concerned it is just speculation because I have heard nothing official. There is no question that he could play at a higher level eventually but newspapers have a habit of raking up stories that are not necessarily true."
He collected the Man of The Match Award against Watford earlier in the season and at the time said: "It is amazing to play in front of more than 24,000 at Bramall Lane. This is what I wanted, to play in the first team and coming from Sheffield and being a Blade makes it even more special."
