Ollie says Birmingham game is a must win after Leeds defeatLions boss Ian Holloway admitted his frustration with the two goals his side conceded in Saturday's defeat to Leeds United.
Millwall began brightly at Elland Road but fell behind when striker Matt Smith flicked Connor Wickham's throw-in past David Forde to open the scoring before Whites skipper Ross McCormack doubled their advantage a few minutes before the interval.
DJ Campbell came off the bench to slam home a stunning 25-yard strike to halve the deficit in the 72nd minute, but Brian McDermott's men held on for a win which keeps Millwall in the Championship's bottom three.
"It's a frustrating one for all of us," Ollie said. "We started well but then their big lad has just gone and flicked one in from a throw.
"I thought we could have done better with the second goal as well. We created a lovely move on the touchline just in front of me but should have played a ball over the top because their defence was high. But they won a tackle and somehow McCormack has stuck it in from a tight angle. I thought we may have had someone closer to him.
"I'm delighted with the second-half, though, and the goal that DJ scored was great. But we're running out of games. There are nine left and we have to start improving our points total, it's as simple as that.
"We still haven't scored two in a game since I've been here but I do think the goals will come. It isn't easy but we're not feeling sorry for ourselves because we have to get on with it. I thought we would get something today and I believe our performance deserved a result. We owe the fans one.
"The Birmingham game is a massive one for us now. We have to try and drag them into it.
"It's a must win. I've never had a more important game in my life."
