Sheffield United boss Paul Heckingbottom keeps a football stud on his desk to remind him of their play-off heartbreak at the hands of Nottingham Forest last season.
The Blades met the Reds in the Championship semi-finals which saw Steve Cooper's side emerge victorious 3-2 after a penalty shootout.
But former goalkeeper Brice Samba came to the Reds' rescue when he made a terrific save to deny Iliman Ndiaye with his studs late on in extra time, which, had he scored, would have given United victory.
