Chopper "disappointed" for players after late Brentford comebackInterim Millwall manager Neil Harris said his players were "outstanding" and deserved all three points from Saturday's dramatic 2-2 draw with Brentford.
Lee Gregory's 28th-minute opener and Aiden O'Brien's first senior goal handed The Lions a 2-0 advantage heading into the final five minutes but Alex Pritchard (penalty) and Moses Odubajo secured Brentford's devastating last-gasp comeback.
But Millwall's display - in front of a vocal away following - was excellent, and boss Chopper rightly praised the efforts of his players.
"The level of performance, the goals we scored and the chances we created were very impressive," he said.
"My boys were outstanding and we deserved to win that game of football.
"I'm disappointed for the players because I know what it's like to be in that situation as a player. It's difficult, but we have to go again.
"We knew Brentford would have that spell and you just hope you can ride it out. Unfortunately the penalty gave them the momentum they needed to push on.
"Even at 2-2 we had chances to win the game but it didn't quite happen for us."
Chopper was full of praise for goalscoring duo Gregory and O'Brien, who put in superb performances up front for Millwall.
"It will be the first of many goals for Lee playing in this style of football," he said.
"His movement is just so good and he is a fantastic finisher.
"I'm delighted for Aiden because he will remember his first professional goal for his whole career.
"It was a great move and he made a brilliant run to be there at the far post to get it in."
