NEIL Harris has been preaching the "Millwall way" to his players since taking charge at The Den, according to Aiden O’Brien.
Harris' Lions produced an energetic and spirited performance against Brighton on Tuesday but were forced to settle for a point in a 0-0 draw.
But O'Brien, who has started in both of Harris' first two games at the helm, says the club legend has had an immediate impact on the atmosphere in the dressing room.
"Neil has been telling the players that the Millwall way is passion, pride, work ethic and giving your all," said O'Brien.
"The fans will back us if we give them that. If we give our all for the fans, show that we're up for it and work hard for the team, they'll be with us.
"The fans were unbelievable against Brighton – they kept us going and we can beat anybody with them on our side. We need to keep performing like this until the end of the season.
"Neil has experience of being in the dressing room so he knows what the fans want – he's played for them and is the club's all-time leading scorer.
"He knows exactly what we need. I'm not saying that Ian Holloway didn't know, because he did, it just didn't work out for him.
"We're performing well under Neil except for putting our chances away.
"He's told us exactly what we're doing, how we're going to do it and there are no grey areas. He told us 'if you don’t like it, see you later'.
"Everyone's got the message straight away and we're together as a group now. We know that we have to stick together as a team at this vital stage of the season.
"We've been tight in midfield and defence, and we've been organised. Now we've just got to put the ball in the net."
Meanwhile, Millwall have announced that Paris Cowan-Hall's ankle injury will keep the winger out for around three weeks.
