This week's featured match is the Dundee derby from almost exactly five years ago and it was one to remember for the Dark Blues.
United were unbeaten in nine derbies (seven wins and two draws) and you had to go back to November 2004 for Dundee's last success - 1-0 thanks to a late John Sutton goal against their city rivals, who had Chris Innes and Mark Wilson sent off.
Jackie McNamara's men had already won three derby matches in 2014/15; 4-1 at Dens Park in the Premiership then 1-0 at Tannadice in the League Cup three days later, before a stunning 6-2 home victory on New Year's Day.
Dundee United had topped the table in November and were second at Christmas but the loss of Gary Mackay-Steven and Stuart Armstrong to Celtic was a blow and they went into this midweek fixture on a run of nine games without a win.
Dundee, meanwhile, had put together a sequence of just one defeat in 11 Premiership matches since shipping six goals at Tannadice on January 1 and were in seventh spot, three places and five points below their rivals.
