United defender Andy O'Brien will tread new ground on Saturday when he steps out at the Den.

During a professional career which has spanned over a decade, the central defender could be in line for a first when he pulls on a Leeds shirt this weekend.

"I've never played at Millwall before," said OB. "I know there's a close rivalry between the two teams, but that's irrelevant in a way because it's a game of football, 11 v 11, and it's all about the three points."

United head for the Den on the back of an important win against Nottingham Forest last weekend, and the second automatic promotion spot will remain within touching distance of Leeds can pick up a maximum return at Millwall.

"This week has gone quick after the Forest game, it's certainly gone quicker than the international break after we lost the game at Sheffield United," reflected Andy.

"There's a good attitude here. We're at the business end now. We want to win all seven games. I know people have said there'll be ups and downs, but while it's mathematically possible to get second we can't have any downs.

"Norwich are six points ahead of us, but we know we have to go into games and win them. We know if we every game the worst case scenario is that we will be in the Play-Offs, best case is we will get promoted at QPR on May 7th.

"It's clear to us what we have to do and the results of other teams are irrelevant.

"There are situations like when Forest went to Scunthorpe and lost and Norwich played Bristol City and we were looking for them to drop points, but now isn't the time to look at permutations. We have to look at ourselves and what we can do."
