Chopper reviews Saturday's 2-0 defeat to Watford
Neil Harris said he couldn't fault the effort of his Millwall players during Saturday's 2-0 defeat to Watford at The Den.
Goals from Matej Vydra and Adlene Guedioura helped The Hornets continue their promotion push at the expense of a Lions side who were clapped off by home fans at half and full-time.
And interim boss Chopper, whose men face a crucial game against relegation rivals Wigan Athletic next up, said his players were feeling positive despite losing out in SE16.
"I'm frustrated and disappointed but the boys have given me everything I've asked for yet again," he said.
"We had numerous opportunities but just couldn't get the ball in that net.
"The players are disappointed but at the same time they are feeling positive in the dressing room because they can see the progress we are making.
"The good thing is that the fans have clapped us off. I think they are identifying with the team and the performances, so that is a positive for us.
"We are getting crosses into the box and creating chances. All that was lacking in the end was the finish.
"On another day we might have had two penalties too, but I'm not going to complain about that because we can't change what has happened.
"We now have a massive game against Wigan on Tuesday night. This is a results business and with the situation we're in we need to be getting wins on the board now."
