"We're looking to the future," says the managerNeil Harris has spoken of his "delight" at capturing the signing of Jed Wallace on Thursday morning.
The winger, who joined The Lions on loan from Wolverhampton Wanderers last January, played 12 times before being recalled in March by then manager Kenny Jackett, scoring one goal.
Wallace has re-joined the club on a temporary basis until the end of the campaign and the manager told millwallfc.co.uk his reasoning behind signing the winger for a second time.
"I'm delighted [to get the deal over the line]," he said.
"Jed came in for a period last season and gave us a real lift. He gave some real strong performances, too.
"We've been in a really good place on the pitch in the last few weeks. We need that competition for places and to have players that can be called upon when needed.
"Jed knows us and enjoyed his time here. Last year, he was a short-term gain, but this year, we're looking to the future - he's a young man. Jed's focus is to come in and help us make sure we're in the top six come the end of the season."
After remaining unchanged for six matches - a run stretching back to the 3-1 victory over Charlton Athletic on December 21st - this Saturday's trip to Bradford City begins a period of 14 games in eight weeks for Millwall.
Harris told of the need to add to the squad in what will be a testing period for The Lions.
"We've been on a good run and been fortunate with injuries and suspensions. Everyone has contributed.
"I've spoken before about having a 19-man squad - Jed now makes that 20. There's going to be disappointed people not to get in the squad, let alone the team, but we've got a lot of games coming up - a lot of midweek ones, too.
"There's no way my players can play Saturday-Tuesday every week, so there's going to have to be changes.
"We've got a real good spirit and desire in the group and while everyone wants to play, if they're not going to be in the team, they all want to support their team mates."
