Chopper displeased with his side's display in Saturday's defeat to WycombeMillwall manager Neil Harris couldn't hide his disappointment following Saturday's last-gasp 2-1 defeat to Wycombe Wanderers, which saw The Lions exit the Emirates FA Cup at the Second Round stage.
Michael Harriman scored the winner four minutes into stoppage time after Ben Thompson - with his first goal for Millwall - had cancelled out an opener from Paul Hayes.
And Harris, who was forced into several changes to his starting line-up, slammed the performance put in by his side at The Den.
"There was only one team on the pitch who played like it was a Cup tie and that was Wycombe," he said.
"I was upset with the team for the performance over 90 minutes. It was below par from us.
"I reminded the players (at half-time) that they were playing an FA Cup game against a team that was committed, direct and who came with a game plan to get about us and bully us. In the first-half we let them do it.
"In the second-half we competed much better but it still wasn't good enough by our standards.
"Younger players will learn as they go but senior players have got to be better and mentally stronger. We need to see more leadership in the team during games like that.
"Overall we were second best. We didn't compete all over the park."
