IAN Holloway believes Liam Feeney's loan exit to Blackburn Rovers will give Lee Martin more clarity about his role at the club.
Martin set up Millwall's winner against Derby on Saturday and was praised for his display by Holloway after the game.
The winger had not featured for the Lions in three weeks prior to the win over the Rams, with Holloway revealing last week that the 27-year-old was "working on one or two things."
Feeney, meanwhile, has moved to Ewood Park until the end of the campaign, but Holloway is not concerned that his departure leaves Millwall short of wide options.
"Lee was terrific, I have to say that," he said. "Feeney has gone off to Blackburn and I think we've almost had one or two too many in the squad who have confused the issue.
"Hopefully I can clear that and make sure everybody knows where they stand. We're going to be a little bit short because of injuries so people have got to step to the plate.
"Sometimes less choices gives you more stability to the group because certain players know they will get the chance to play through some problems."
Holloway was also impressed by captain Paul Robinson's substitute cameo after he replaced the injured Danny Shittu midway through the second half.
"Did I expect anything different from that young man?" the Lions boss added. "He's Millwall through and through. If you cut him in half, he's got Millwall in his blood.
"He will get a chance at Blackpool tomorrow."
Alan Dunne returned at right back at the weekend but Holloway will assess before the trip to Bloomfield Road whether the 31-year-old is ready to play back-to-back games.
"I've also got to look at whether Dunney can play two games in three days because he hasn't played for a while," he said.
"I could put Ryan Fredericks back in if I wanted to so that Dunney will be fresh for Charlton, so these are the kind of things I have to weigh up."
