NEIL Harris reckons the enthusiasm and hunger of Aiden O'Brien is rubbing off on the rest of the Millwall dressing room.
O'Brien headed in his first senior goal as the Lions drew 2-2 with Brentford on Saturday.
Harris hopes that O'Brien breaking his duck will lead to further goals – but isn't putting any pressure on him to score regularly.
The Millwall boss says the 21-year-old has already been making a vital contribution to the team with his attitude and work ethic.
"It's not necessarily about goals with Aiden – it's his energy, pace and, like Lee Gregory, he's so direct," Harris said.
"Every time he gets the ball, he wants to go towards goal. He's a character as well – he's hungry to play and people bounce off him.
"He's a bubbly lad and for one so young, he's got a good standing in the group.
"That gives Aiden the belief that he belongs out there with the first team, so scoring against a top team like Brentford will reinforce that confidence.
"Hopefully he'll now kick on but, again, there's no pressure on Aiden to score the goals. I want him to keep his performances going first and foremost.
"What he did for the U21s has led to him getting an opportunity in the first team so I want him to play exactly the same way.
"He should try things on the ball and if he loses it, win it back and try again. I want Aiden to enjoy himself."
