Neil Harris admits he “got it wrong” tactically during the first-half of Millwall’s defeat to cross-city rivals Queens Park Rangers at Loftus Road.

Former Lions youth player Ebere Eze followed up a Massimo Luongo opener to give the hosts a comfortable two-goal cushion in the opening 45 minutes.

Tom Bradshaw was picked to start with Lee Gregory before he was replaced at the break with captain Steve Morison who was benched for the clash.

But Harris says he is the one to blame for Millwall’s ineffectual start to the game which saw them fail to register a single shot on target all first-half.

He said: “I take full responsibility for picking the 11 I did, and the tactics in the first-half. I hold my hands up and say I got it wrong. No problem with that.

“What I will bemoan is my players' lack of fight in the first-half. We played in a London derby against a QPR side that were up for it, and played aggressively, and on the front foot, and used the ball better than us.

“We didn't compete in the first-half, we weren't good enough, we weren't Millwall enough but ultimately we've lost to two really, really crap goals.”

The result leaves Millwall a point from the drop, with just one win from their opening eight Championship games this season.

They travel to the Hawthorns in a major test against former Premier League side West Bromwich Albion who dispatched their midweek opponents 7-1.

While Harris said the form is concerning, he is clear on what needs to be done.

He added: “It's a concern because we've not won in a few weeks. [Then again] it's not a concern because there are various factors to our disappointing results - from late goals to issues off the pitch around the transfer window. However, I'm disappointed today with the first-half because my Millwall team doesn't normally get outrun and outfought and in the first-half we did.

“I look at it tactically rather than question individuals. What I do know, moving forward, is we'll get better. We will get results because that's what we do every year, we start badly and we kick on. But I have to pick the right team on Saturday at West Brom in a difficult fixture, but I'll pick a team that's more Millwall-like.

“Let's get it right: we should have beaten Middlesbrough first day of the season, we should have beaten Leeds on Saturday, we beat Derby, we should've been out of sight against Swansea - against 10 men - we drew at Blackburn who have proven a really good side. We're disappointed to lose at Sheffield Wednesday.

“We're not a million miles away and we showed that in the second-half, I just got it wrong in the first-half today.”
