With United embedded in the play-off zone, this difficult tie will represent an opportunity to solidify their position in the top six with Millwall looking for revenge for the 3-1 defeat to Leeds suffered at Elland Road at the beginning of the season.

Leeds’ games against Millwall have become notorious in recent years due to a spate of clashes between rival fans after matches. Both sets of fans have become infamous for a small minority of violent fans, ensuring that this remains one of the most combustible football matches on the calendar.

However, it is hoped that it will be the football that takes centre stage. Leeds are looking to improve a run of form that has been typical of this season. They have followed fine victories over Doncaster and Preston, and the phenomenal 4-1 victory over play-off rival Nottingham Forest last weekend, with the dismal 2-0 defeat away to relegation haunted Sheffield United.

Leeds will be missing Billy Paynter, serving the second of a three match ban for his dismissal at Sheffield United, but welcome Jake Livermore on loan from Tottenham Hotspur and, with Johnny Howson back from a slight injury in the victory over Nottingham Forest, will be hoping to name a very strong starting line-up.

Likewise, Millwall have had mixed form this season. After February and March had seen a run of just two points from five games, recent games have seen Millwall defeat the likes of league-leaders QPR and relegated Premier League sides Hull and Burnley. With a strong record against teams at the top of the table there is real potential that Millwall could provide a sterner test than their mid-table league position suggests.

Such a temperamental clash will be a great test of Leeds’ resolve and their ability to stay in a promotion race they were not expected in many quarters to be a part of. Millwall’s recent good form will make this a game that could well be key to Leeds’ fate.

Leeds will be hoping that this is not the beginning of a strong late promotion push from Millwall – and that they can keep their own promotion charge on track.
