Sheffield United and Sheffield Wednesday have met a total of 116 times in league and cup, stretching back to the very first meeting on 16 October 1893. The Blades hold the edge, with 42 wins to the Owls' 37, and 37 draws.
The very first match - in the old Division One - ended with honours even after a 1-1 draw, but it was the Blades who notched the first derby win in the second meeting just a month later, with a 2-1 victory on 13 November 1893.
The Owls had to wait until 7 September 1895 to post a first win over their city rivals, beating the Blades 1-0 in a league clash.
But their joy at getting one over the Blades was short-lived as the Owls would have to wait until the turn of the century and 11 matches before their next victory - a 1-0 success on 29 April 1901.
The teams have met six times in the FA Cup - with the Blades winning the first three meetings (1900, 1925, 1928) and the Owls the last three clashes (1954, 1960, 1993).
The very first meeting in the FA Cup was a second-round clash in 1900, which the Blades won 2-0 in a replay after a 1-1 draw in the first game.
The most recent FA Cup meeting - and perhaps the most famous Sheffield derby of them all - was the 1993 semi-final at Wembley, won 2-1 by the Owls after extra time.
