NEIL Harris has hinted at changes to his team for the south London derby with Charlton next week after Saturday's 3-0 loss at Scunthorpe.
Paddy Madden scored with a free header from Josh Morris' free-kick to put the Iron ahead, before Millwall lost the ball deep in Scunthorpe's half and were punished on the break when Hakeeb Adelakun doubled the lead just before half-time.
Madden made it 3-0 in the 67th minute after Jordan Archer had sprinted out of his box to head away only for Morris to gain possession and set up his team-mate.
"There was nothing in the game for 90 minutes except that we made three errors," Harris said. "At this level against a team that's top of the league you can't make errors, you can't make basic errors. It's just not acceptable.
"If I can't trust people to do the right things, people making the same mistakes, then I'm picking the wrong players. However good they might be at doing something else if they can't do their jobs properly they can't play.
"We were looking really comfortable and a real threat on the turnover of possession. We're away from home against one of the best teams in the league and getting into really good areas.
"What I would say is today we were nearly men with the ball. We got into really good areas around the box but didn't quite have the end product.
"It's not quite happened for us the last two games in front of goal, but it will because it's happened for us all season. That will come.
"But for me you can't give the team at the top of the league opportunities like we did. I'm disappointed with my players for that. I think they've let themselves down as a group with those errors.
"There's nothing between the teams and we come off having got beaten three-nil.
"It's the same young players making the same mistakes. It's hugely naïve. We accept there are going to be errors from young players, of course we do. But I don't expect the errors now, I expected them last season or at the start of the season.
"We have to make better decisions with the ball and without the ball. We're making slight errors of judgement and the ball is ending up in the back of our net.
"I have to take responsibility as the manager and ask if I'm picking the wrong players."
