The atmosphere at Bramall Lane will be supercharged when Sheffield United and Nottingham Forest run out to do battle in the first leg of their Championship semi-final play-off this weekend.
Not only are the Premier League ambitions of two historic clubs and a promotion dividend of more than £100million on the line, but matches between the Blades and the Reds reverberate with almost 100 years of history.
Last time the two sides met at this stage of the play-offs was 19 years ago. United battled back from two goals down in the second leg, to snatch a 4-3 win in extra time on a crazy, raucous night in Sheffield, in 2003.
