Chopper delighted after second-half goals secure third straight victoryMillwall manager Neil Harris described his side's performance as "outstanding" as The Lions stretched their unbeaten away record to four games with a 2-0 success at Port Vale.
Mark Beevers headed Millwall in front on 58 minutes before Lee Gregory, on as a second-half substitute, scored a penalty which he won himself during stoppage time.
The Lions created numerous goalscoring opportunities, especially during the first-half, in a game which they dominated for large spells against a powerful Vale side.
"I'm delighted," Harris said. "There were some big individual performances out there but the team's display, as a whole, was outstanding.
"It was tough to go again after playing so well and getting a result at Crewe on Saturday, but we managed to carry the momentum on.
"By half-time it could have been five or six-nil to us. We created a lot of opportunities and it was pleasing that in the second-half we were rewarded for our play in attack with the two goals.
"They handled us better after the break and it was much more of an even game, but when you have the goalscorers that we do then you can cause teams problems and we did just that."
He added: "Tonight we dominated, certainly in the first-half, possession-wise because we had the energy and we had the movement. Players wanted the football.
"We have a strict game plan in and out of possession but players have to have the freedom to make their own decisions.
"At the moment we seem to look like a proper team."
