Aiden O’Brien says the hostile atmosphere at the Den has a negative effect on visiting players.

The winger helped Millwall to their first league win of the season after beating Norwich 4-0, with goals from Lee Gregory, George Saville, Jed Wallace and Shaun Hutchinson.

O’Brien believes the Lions’ Championship rivals will hate coming to Zampa Road this season.

O’Brien said: “On a personal note, the hostile crowd gets me going. It gives me that extra five or ten per cent to just get back, make a tackle or bust the gut to get back into the box to try and clear a ball.

“When the crowd are on their game, it plays a massive part to how we want to play. When they are shouting and screaming, doing all the chants like ‘Millll’, the opposition players crumble.

“You can see it, they do not want the ball, they make mistakes and as soon as they make mistakes, we pounce and we are off. It 100 per cent has a negative effect on opposition players.”

Millwall have lost just twice at the Den in 2017 and their home form will no doubt be the catalyst to a strong season.

O’Brien added: “Every team will hate to come and play us at The Den because they know what we do, the way we play and the way we set up, not many teams can stop it, if anyone. I do not think anyone can stop it when we are on our game like today [Saturday].

“When the ball goes up to the forwards and they are on their game and they nod it down and we have got runners off the ball, it is frightening.

“You can see it, no one is ready for it. We know what we are doing, they do not know what we are doing. We are already ahead of the game. It is impossible to stop when we are flying and it showed today.”

Next up for Millwall is a trip to promotion hopefuls Wolves on September 9, but O’Brien does not think the two-week break will hinder their momentum.

He said: “Hopefully we can keep this momentum going. I know we have a break, that has come at the wrong time, but that means nothing.

“We will keep doing what we are doing on the training pitch, dressing room, listening to the staff and I believe we are good competition.”
