Neil Harris wants to put things right against Brentford tomorrow after being “robbed” in the reverse fixture.

The Lions were beaten 1-0 at Griffin Park in October in a game marred by controversy.

Lee Gregory scored after Jed Wallace was tripped in the box, but referee Lee Probert failed to play an advantage and awarded a penalty. Gregory stepped up and missed his 81st-minute spot-kick.

Ahead of the Bees’ visit to the Den, Millwall boss Harris told News Shopper: “It left a bitter taste.

“It was a game that I felt we deserved maybe three points, let alone one.

“We were robbed by the referee’s decision rather than Brentford.

“They dominated the first 45 minutes and the second-half was one-way traffic from us. How we didn’t win the game or at least get a point, I think was a travesty.

“But when you lose a game, you want to get your own back on the opponent and Saturday will be a top game.”

Millwall, who are on a 10-game unbeaten run, will leapfrog play-off-chasing Brentford with a victory in SE16.

The Lions will need to replicate their impressive February form if they are to make a late push for the top six.

Harris is wary of the attacking threat posed by Brentford – in-form forward Ollie Watkins has scored four goals in his last three games.

He added: “Brentford are a top side. I love watching them play. With their style of play, they get the ball on the floor, and pass it but don’t be fooled, they go direct as well. They play a lot of long balls forward and do it with a purpose.

“They’re a really impressive footballing side. [Brentford manager] Dean Smith has done a great job. They’re knocking on the door of the play-offs again.

“It’s an interestingly run club, there’s been a lot of financial backing to bring players in off the back of the Moneyball scenario.

“They’ve got some super players, who are attack-minded. It’s going to be a very good London derby and it’ll be a really good atmosphere with both teams wanting the points.

“Brentford will put us under pressure at the Den and we’ve got to be at our best defensively to deal with their attacking threat. But we know we’re more than capable of causing them huge problems.”
