Chopper lauds attacking play as O'Brien and Gregory find the netMillwall boss Neil Harris was pleased with the comfort in which his side secured their passage to the Johnstone's Paint Trophy Area Quarter-Finals at The Den on Tuesday night.
Aiden O'Brien and Lee Gregory scored second-half goals to help The Lions beat Northampton Town 2-0, but The Cobblers had goalkeeper Ryan Clarke to thank for keeping the score down after a string of impressive saves.
And Chopper, whose side are now without a game until October 17th, praised his side for their attacking play in SE16.
"I thought in the end it was quite comfortable for us," he said.
"At half-time it could've been 3-0 to us but we had to be patient to get that first goal. Once we did it could've been more comfortable than 2-0 but their goalkeeper was probably Man of the Match.
"We saw another team come to this ground and try to frustrate us by keeping the ball. The game is different these days so you can't always press it; it's about what you can do with the ball in the final third that matters and we looked good in attack tonight.
"We saw a lot of effort from the group with the players who were out there showing how desperate they are to impress."
Harris handed a start to new loan signing George Saville and was full of praise for the midfielder's performance.
"I thought George's second debut was outstanding," he said.
"For a boy who hasn't trained for three days and hasn't played a lot of football I was really pleased with how he did.
"He will only get better the fitter he gets so it's great to have another option in the midfield."
