Derby County Football Club have failed with an offer for Conor Sammon.
The former Republic of Ireland Under-21 international has been in great form this season, scoring fifteen goals in 23 appearances in the Scottish Premier League.
According to skysports.com, such form has caught the attention of Rams manager Nigel Clough, who has offered £425,000 for the 24-year-old.
However, this bid falls short of the valuation Kilmarnock have of the striker, and it remains to be seen if the Championship club will make a renewed attempt for his signature.
