MILLWALL boss Neil Harris admitted his side lacked creativity in the 2-0 loss to Bolton Wanderers on Tuesday night.
The Lions conceded in the second minute to Sammy Ameobi and then four minutes from time and in between they struggled to test Bolton goalkeeper Mark Howard.
Howard saved from Steve Morison's close-range header in the first half but otherwise he was well protected by a defence that was marshalled superbly by ex-Millwall defender Mark Beevers and David Wheater, who got the late clinching goal.
Millwall's most productive supply route was on the right through Fred Onyedinma and Mahlon Romeo, but Bolton rarely left any space in the box for strikers Morison and Lee Gregory to test Howard.
Harris introduced Shane Ferguson and David Worrall in the second half, but Millwall couldn't break down a Bolton side that kept a fourth consecutive clean sheet and stopped the Lions from scoring for the first time since April.
"We had a right go at Bolton but they were very good, fair play to them," Harris said.
"It's tough because we were a really solid side that performed so well at Northampton. I thought we were really good in the first half (Tuesday night), barring the first 10 minutes.
"But we lacked that little bit of creativity. I thought Mahlon and Fred linked up really well down the right-hand side in the first half, though we didn't create as much on the left side.
"Then you make the changes in the second half because you're chasing the game. You put your positive players on and try and put players on that can deliver the football into the box.
"Maybe at key moments we didn't quite have the run of the ball in the penalty area. There were a lot of 'oohs' and 'aahs' but no real clear-cut chances and that was the frustration."
