The manager speaks following goalless draw with The Saddlers
Millwall manager Neil Harris was pleased with a clean sheet in Wednesday night's 0-0 draw with Walsall, but stated his frustrations at not being able to win the game.
In an evening of few chances, The Lions could not find a way past The Saddlers, meaning both sides had to settle for a point.
The result, meanwhile, does mean that Harris' side are now unbeaten in nine games in all competitions.
"I thought we started the game really well," Harris said.
"For 25 to 30 minutes, I thought we moved the ball well, got into good positions and got balls into the box. We were a little bit reactive in the area on crosses and set-plays, which is unlike us.
"Walsall stifled us a bit up until half-time, but I thought we'd kick on in the second-half and get stronger as the game went on. I thought we'd have spells where we'd lay siege on their goal and create chances, but it never quite materialised.
"In the last 20 minutes, we were a bit sloppy. A bit of calmness disappeared from our game. Where we'd been so effective and creating chances and playing the Millwall way, it all disappeared towards the end.
"I've said to my players that if you play well in the first 20 minutes, you've got to play well in the last 20 minutes - especially here at The Den.
"I'm a little bit frustrated that we didn't work their goalkeeper a bit more, but I'm pleased with the clean sheet."
