United manager Simon Grayson says there will be no room for complacency as his side look to extend the advantage at the top of League One on Tuesday.

Grayson's men take on Leyton Orient at Elland Road on the back of a run that has produced three victories, 11 goals for, and none conceded.

United are also unbeaten at Elland Road in the league since January, and the Orient game could see that unbeaten run extended to 20 games.

"I said to the players before game at Brighton on Saturday that it's one of the biggest we have played," said the boss. 

"Now I don't want anyone thinking because we are at home to Leyton Orient they can just turn up because they would be in for a rude awakening. 

"I  genuinely feel we have a group who won't allow complacency to sneak in. We've got individuals who will get onto others if they see anyone slacking in training and games. We need to keep focusing and doing the right things.

"We're not a complacent group, we're a confident group, playing with a lot of belief and desire.

"We're six points clear and we have to keep pressing and pressing try and pull away from teams as quickly as possible.

"There's some big teams below us and they have had some good runs. Huddersfield have done well, Charlton have picked up again, and Norwich are there.

"We'll just keep doing what we're doing and affect what we're doing."
