IAN Holloway says his Millwall side need to tighten up their defence ahead of Saturday's Championship clash with Derby County.
The home fans booed their side off at the break after goals from Clayton Donaldson and David Cotterill put the Blues is command.
Holloway's double half-time change saw Richard Chaplow and Aiden O'Brien enter the fray and their introduction livened up the hosts with Lee Gregory reducing the arrears nine minutes after the restart before the visitors got a third.
Holloway said: "We've got to stop defending like that, we've got to stop the long ball getting hit over our head and them scoring.
"They've had four shots and scored three.
"It is very déjà-vu, so we've just got a lot of work to do."
The Lions are now without a win in five games after an impressive start to the season, form which has seen them tumble alarmingly down the Championship table from the play-off places.
Holloway said: "It is a good job we had that good start because it would be a lot worse now if we hadn't of won those first two games, wouldn't it?
"The positives for me were that no-one folded. We had a terrible spell where we go in at half-time 2-0 down and we managed to get ourselves back in it - and for all intents and purposes I expected to get something.
"I thought the crowd were great, I thought they loved the fact Aiden O'Brien came on. I thought he did fantastically well."
THE acting chairman of Birmingham City, Peter Pannu, will not have his contract renewed by the club.
The Blues have issued a statement which reads: "Birmingham City Football Club can confirm that the service agreement of Peter Pannu will not be renewed beyond 30 September 2014.
"Panagiotis Pavlakis (Panos) will continue to act as representative of the BCFC Board in the UK and oversee the day-to-day running of the club with full support from the UK management team.
"BCFC wishes Mr Pannu all the best for the future."
Pannu signed a consultancy agreement with Carson Yeung for five years in September 2009. It was through his company Asia Rays Ltd.
