Billy Sharp accused Wrexham of being disrespectful and hit out against the referee after helping Sheffield United reach the fifth round of the FA Cup.
Sharp scored as the Championship promotion hopefuls prevailed 3-1 in an enthralling cup tie in the replay at Bramall Lane on Tuesday night. Sheffield United will play Tottenham in the next round after scoring two late goals to capitalise after Paul Mullin saw his second penalty saved by Adam Davies.
Anel Ahmedhodzic had put the Blades ahead early in the second half before Mullin equalised from the penalty shot with a thunderous strike. Mullin saw a second spot-kick saved by Davies before the home team struck late to seal it.
