Interim boss Chopper shares his opinion on 0-0 drawNeil Harris felt his Millwall side did enough to earn all three points from Saturday's 0-0 draw with Cardiff City.
The Lions created a number of opportunities against the Welsh side, mostly during the second period, but couldn't find a way past Bluebirds keeper David Marshall.
The draw sees Millwall close the gap between them and Rotherham in 21st-place to four points but Harris admits his side could and maybe should have reduced it further.
"Cardiff were probably the better side in the first-half but in the second it was chance after chance for us," he said.
"On another day we certainly win that game. Unfortunately it just didn't quite happen in and around the six-yard box for us.
"But overall we have shown how far we have come with that display. Our performance deserved more.
"It's another step forward because the boys know they have played well.
"We're pleased with the clean sheet against a good Cardiff team. They have a number of quality players so they defence had to play well, which they did.
"It gives us a good base going into Tuesday's game against Blackburn. We will give it a right go up there."
