Leeds United are eyeing a bumper 30,000-plus crowd for Saturday's home humdinger with promotion rivals Norwich City.
The third-placed Canaries have already sold out their full allocation of around 2,300 for the mouth-watering fixture which pits together two of the Championship's in-form sides.
And with home tickets selling fast for the clash, only designated as a Category B fixture, the attendance could go close to United's biggest home league attendance so this term – 33,622 for the White Rose derby with Sheffield United on September 25.
United have attracted three crowds of over 30,000 in the league this term, with their current average of 26,668 the best in the division and higher than six clubs in the Premier League.
The Whites go into the clash buoyed by impressive back-to-back victories over Bristol City and Coventry City, and having seen their colours lowered just once in the league in the past 18 matches.
Paul Lambert's City – who battled it out with United for the League One title last year – are also running hot and have been beaten just once in their last 10 Championship games and twice in their past 17 league matches since the start of November.
Victory would see United leapfrog the Canaries, currently two points clear of them in the table and it promises to be a seminal weekend in the battle for promotion with second-placed Cardiff City visiting Nottingham Forest, in fourth as four of the top six square off.
