IAN Holloway will push ahead with his plans to overhaul Millwall's squad during the January transfer window after a 3-1 defeat to Ipswich Town on Saturday.
The Lions boss was "encouraged" by his side's spirited performance against the second-placed Tractor Boys but says he needs to add more new signings to his squad.
Holloway has brought in five players so far this month and four of them – Shaun Cummings, Dan Harding, Diego Fabbrini and Stefan Maierhofer – started against Ipswich.
The Millwall boss made eight changes in total to his starting XI following a humiliating 4-0 loss to Bradford City in midweek.
Noel Hunt scored twice inside the opening quarter of an hour to put the visitors in control and although Magaye Gueye pulled one back, Jonathan Parr put the result beyond doubt.
Despite the result, the Lions were clapped off at full time.
And Holloway said: "It needed to be a spirited performance after Wednesday, didn't it? I think everybody understands what I'm about and what my teams normally do.
"The atmosphere and the way the crowd stuck with us after going two goals down in 14 minutes was absolutely terrific because they could see the spirit of the lads.
"I've been given the job of turning this squad around to make it win in the Championship.
"Andy Ambler and I believe that we have to make some decisions very, very quickly and bring forward a process that we were going to do next summer.
"We want to make a lot of changes and add some new players because the secret will be from outside and not within.
"I know which young ones will have a big future for us and be Millwall legends of the future but I need to make some decisions for my group to give them some clarity.
"I need to move things on immediately and that's what I'm going to do.
"We've got ten days until our next game to fill people in about where they are and see if I can facilitate them moving out.
"You saw four new players and Paris Cowan-Hall will be fit for next week but there are elements that I need to put right because there is worry whenever a team gets near our goal.
"It's very difficult to have that but, at 2-0 down after 14 minutes, the crowd were absolutely magnificent because they stuck with the lads and the lads felt that and got back in it.
"I was pretty encouraged. But if you look at the second goal, their bloke has run off the pitch and then comes back on and scores.
"I believe the fans understand what we're trying to achieve.
"It's not good enough at the moment but we've got 20 games left and hopefully I can clarify who is and isn't going to be here.
"Whoever that is, I can tell them and try to move them out, and bring others in.
"The secret will be who I manage to bring in now because we're letting too many goals in and we're not scoring enough."
