Millwall boss Neil Harris stated that there were plenty of positives to take from Tuesday night's 2-1 defeat to Sheffield Wednesday in the Sky Bet Championship, but felt his side could have taken at least a point from Hillsborough.
Adam Reach nudged Wednesday into an early lead, but Tom Elliott's fourth goal of the campaign levelled matters in the 12th minute.
However, Jordan Rhodes' header just before half-time won The Owls the game. Jake Cooper was shown a second yellow card late on for Millwall.
"I think Sheffield Wednesday were excellent for the first 20-25 minutes," said Harris. "They showed their quality. Don't get me wrong, we helped them out - our shape and decisions to press the ball were poor and unlike us.
"However, we then got a foothold in the game with the equaliser and between then and their second goal, I thought we were excellent. We were the dominant side. But, it's a poor goal to give away. We can't give top players like Jordan Rhodes an opportunity in the penalty area like that.
"The boys came in a bit disappointed at half-time, but I reminded them of where we are at the moment and how well we've done now up to now - and the second-half was excellent. We controlled the game for 30-35 minutes of it and were the most dangerous.
"We should've scored at least once. I tried to chase the game and be more aggressive with the substitutions. We could've lost a third goal because of that, but that's the risk you have to take. The subs didn't quite have the impact I would've like, but there are plenty of positives to take from tonight."
