Neil Harris says he won’t allow his Millwall players to become complacent.

The Lions are 11 points clear of danger with 15 games remaining.

And Harris is wary of being dragged back into the relegation dogfight.

He told News Shopper: “If I see complacency in the players then they don’t play. That’s the beauty of it.

“If there are things I’m not happy with in the team, if I don’t feel players are performing to what I expect then they don’t play. It’s as simple as that. The players are slowly realising that.

“Complacency? No, it’s not what we allow at this football club. It’s not something we’ve had in the second half of the last two seasons – and it’s something we won’t have this year either.

“We want to keep getting better and keep amassing points. When we got to 30 points, we wanted to get to 40 points as soon as possible. That’s not changed.

“We want to get a positive result at Birmingham on the weekend, get over that barrier and get over the next one. That’s what it’s all about.

“We’re in a healthy position in the league but that can change so quickly. We have to make sure as a group, we don’t step off doing what we’re doing.”
