STEVE Lomas has admitted he wants to strengthen his squad in the loan market after allowing James Henry and Liam Feeney to depart.
Henry, 24, and Feeney, 26, have joined Wolves and Bolton respectively for the next three months, leaving the Lions short of wingers.
Lomas said: "We're looking to strengthen, there's no two ways about it. That hasn't changed since I came in. But we have to make sure we get the right people and for what we can afford with our budget."
Fresh faces would be a welcome boost for the Millwall boss, whose side were well off the pace in their 4-0 defeat by Birmingham City on Tuesday.
"Tiredness could be an easy excuse," Lomas added. "Every game in the Championship has its challenges, and if you don't rise to them you will get found out. It's very frustrating for the fans that travelled up there - we produced a shoddy show and I'm gutted for them.
"In any game of football, you've got to earn the right to play. In our previous three games, we did that and got our rewards. On Tuesday we didn't and we got turned over. We didn't do the basics right.
"We thought about freshening it up after the Leeds game, but we wanted to give the boys an opportunity to keep the shirts. It would have been harsh to drop anyone after another win. But when you lose, that changes and places are up for grabs."
But one player who is unlikely to feature against Bournemouth on Saturday is striker Scott McDonald, who has had a second injection on a knee injury.
"He has had a sugar jab now so we will have to wait and see with Scott," Lomas said. "He's already had an anti-inflammatory injection.
"We will have to decide whether it is worth risking another potential setback against Bournemouth, or give him the two-week international break to recover. We will be guided by what the physio says."
Meanwhile, Josh Wright could be the next squad member to leave The Den on loan.
"A few clubs have made enquiries but they are just enquiries at the minute," Lomas said.
