Neil Harris bemoaned the way Millwall conceded the second of Leeds’ three goals after his side lost at Elland Road, despite leading twice.

Mahlon Romeo’s poor clearance was pounced upon by substitute Barry Douglas, whose whipped cross was nodded in by Luke Ayling for 2-2.

Before that Millwall were a goal up but would let in a third when Pablo Hernández, who had scored the first equaliser, swept home the winner.

Harris said it was a “poor” goal to concede, adding: “Comes at a time when we're not really under pressure. We're managing the game well, breaking the play up, and it's poor.

“I said to the boys if they want to get to the higher reaches of the division, or even the next level, you can't give goals like that away.

“You can't give good teams like that a foot up in the game.”

However, the Lions boss was quick to praise what his side did well – in its counter-attacking play, defending and overall performance at a “sold-out Elland Road”.

Harris said: “I thought the players, on how they performed for the majority of it, they possibly deserved something.”
