Millwall 0-4 Coventry City

Loanee Adam Armstrong netted a second brace in as many league games as Coventry thrashed Millwall at the Den.

Millwall striker Lee Gregory saw his early penalty saved by Coventry's Lee Burge, and the visitors capitalised.

Armstrong scored twice either side of Ruben Lameiras' strike to put the Sky Blues three goals up inside 25 minutes.

Late on, Jim O'Brien smashed in after a one-two with Marcus Tudgay to see Coventry set the early pace at the top of League One, with two wins from two.

Millwall boss Neil Harris told BBC London 94.9:

"I thought it was a shambles at times to be honest.

"It really hurts to be honest and I'm not sure it hurts some of those players in the dressing room as much as it hurts me.

"We knew they had dangerous players, they had exciting players but we have to impose ourselves on them. We didn't. Some of the players looked like they didn't know how to do it. I'm disappointed with all the negativity.

"I thought we were excellent at Shrewsbury and we were excellent against Barnet at times.

"I think it's clear to me that some of the players are struggling to play here at the moment and until there's some results on the board I certainly have to reflect that in my team selection."
