Sky Sports sources understand Sheffield Wednesday have had a bid turned down by Nicklas Helenius.
The Danish striker has been linked with a move to England throughout the summer and Leicester City and Hull City have both also been monitoring the situation.
Championship new-boys Wednesday have failed in their initial attempt to sign the AAB Aalborg man as they seek firepower for life back in the second tier.
The 21-year-old, who stands at 6ft 5in, was last season one of the top scorers in Denmark with 14 goals for AAB.
Premier League trio Fulham, West Bromwich Albion and Norwich City have in the past all also been linked with Helenius to give a reflection of his talent.
