Millwall boss Neil Harris says his side will be a tough team to stop if they make the play-offs.

The Lions moved up to 7th and extended their unbeaten Championship run to 15 games with a 2-0 victory over top-six rivals Bristol City at the Den.

A stunning goal from Jed Wallace put Millwall in front before captain Steve Morison doubled their lead just before half-time with a left-footed finish after a fine backheel from striking partner Lee Gregory.

Harris said the two goals were a fitting tribute to the late Ray Wilkins, who was given a rapturous minutes applause before the game.

“The discipline was of my players was the as good as it’s been in my time in charge. For all the good play they had, I am struggling to think of a chance in our penalty area, apart from the header right at the end that goes over,” Harris said.

He continued: “I thought the two goals we scored were certainly befitting the man that we had a minutes applause for before the game, because Ray would have loved those goals from those two players, for different reasons. One being an old pro [Steve Morison] that he would have loved working with and one being a young player coming through the ranks.

Wallace’s goal was his seventh in the league this season and he will have to go a long way to score a better one. The 24-year-old picked up a pass from Ben Marshall on the left before unleashing a stunning curling effort into the top-right hand corner.

When asked if it was one of the best goals in his time at Millwall, Harris said: “Yes, I think so. He has got that ability to do that. We like to play in their final third and we like to get the ball their quickly, my fans demand we get the ball there quickly.

“But once they are there, the gloves are off. The players go where they want, do what they want and the first goal was real class.”

The victory means Harris’ side sit just one place outside the top six and just a single point behind Middlesbrough, who occupy the final play-off place.

With games to come against Tony Pulis’ side, as well as a visit to Sheffield United next Saturday, the Millwall boss says his side expect nothing, but if they do make the play-offs, it’ll be a hard game for whoever they play.

Harris said: “We have got ourselves into a really good position, but it’s a different feeling. It’s not Middlesbrough Derby, Sheffield United, Bristol City, Preston, Brentford, who are still coming.

“They think they should be in the play-offs. They expect to be in there and Aston Villa fans expect to be win the play-offs. Fulham fans expect to win the play-offs or get promoted. We don’t expect it. We don’t expect anything.

“All I expect from my players is work ethic and a desire to want to win and if it carries us far enough, it carries us far enough. What I do know, if we did get in there, we will be a tough team to stop in the play-offs, because this will be our third year in a row.”
