NEIL Harris has said more of the academy starlets will get their chance ahead of a return to pre-season.
The Lions come back off their summer break in two weeks and Harris has said the first team, along with some of the U21 players, will be taken to a training camp in Portugal.
And Harris added that the young players who don't travel will have a chance to impress when they return to Calmont Road.
"We're going to have ten days at the training ground where we will work physically with three sessions a day," Harris said.
"Then we will go over to Portugal to do similar, but in an environment where they're living together and spending twenty-four-seven together as a group to build a spirit and a bond between themselves.
"Some of the young lads will get a chance to go. The first team players will go, some of the U21 players, too.
"When they come back they will get an opportunity and, throughout next season, they will be in and around the first team.
"Some will get an opportunity to go to the pre-season camp, some will get a chance when we get back to play a part in first-team games."
Harris also dispelled rumours of a lack of spirit last season, and reiterated his plan for a smaller squad to help limit any frustrations that might develop with players being left out.
"I wouldn't say there was as spirit lacking last season," Harris added. "But I think that, sometimes with a big squad, it brings disharmony at times.
"Everybody wants to play, so it becomes difficult to manage a big group.
"If players aren't in the team they can get frustrated.
"At Millwall, you've got to have a team spirit and a bond within the group to be successful."
