Chopper shares his post-match assessment
Neil Harris felt that his Millwall side gifted Barnsley all three points at Oakwell on Saturday afternoon.
Sam Winnall gave the hosts a 1-0 lead after 12 minutes but Steve Morison scored an equaliser to give the away side hope of victory on the hour mark.
But Lee Johnson's side went back in front just six minutes later when Adam Hammill slotted home, much to the annoyance of the Millwall boss, and held on for victory on a rain-soaked afternoon in Yorkshire.
"We had three off the line, two of which were good efforts and one we should score. I thought we gifted them three points.
"Our decision making defensively was poor as a team and it's frustrating off the back of such a brilliant performance at Southend.
"We weren't at our best but we got back to 1-1 slightly against the run of play, and after that it should only be one team who wins it. The chances dictate that and the ones we had should've meant we went on to win the game.
"I don't think we affected the game in the first-half as well as we could've done, or we did against Southend. We were slow to react to second balls and our movement wasn't good enough. Our use of the ball going forward was poor.
"Second-half we were much better but I have to look at my players to ask why they didn't do it from the first minute."
