MILLWALL don't have the right players in their squad to play a 4-4-2 formation, manager Ian Holloway believes.
Some Lions fans have called for a back-to-basics approach from their side as they bid to secure Championship football for another season.
Holloway, who does not play with traditional wingers, admits Millwall need to improve the quality of their crosses into the box, but he is not about to abandon his tactical beliefs.
"I don't think too many teams are used to playing 4-3-3 as we have been doing, but I don't think 4-4-2 is an option for us having lost James Henry to Wolves," the Lions boss said.
"I am used to having more movement and getting more rotation in those wide areas, and that's something we're working on. That's an ongoing situation.
"I had Yannick Bolasie and Wilfied Zaha at Crystal Palace, and at Blackpool I had Tom Ince and Matt Phillips with Seamus Coleman and Stephen Crainey as the full backs bombing on.
"We are working with two young lads (Scott Malone and Ryan Fredericks) who are doing well, they're improving and giving us width."
But Holloway added: "Henry was our best crosser of the ball and we lost him.
"You can't argue with that fact. That's nothing against the lads we've got because they can get good deliveries into the box."
One winger who has been left out of Millwall's squad for recent matches is Lee Martin, who Holloway explained has been asked to improve on certain aspects of his game.
He said: "Lee is working on one or two things. It's no good me believing things about him if he doesn't believe them himself.
"I have asked him to look at himself and he's doing that. Hopefully he will get over some of the damage that has been done by Manchester United earlier in his career.
"The boy is coming along well and I'm really excited about his future development, whether that's with us or someone else.
"Every one of our individuals has got to blend into the team structure and the team unit.
"Providing I see what I'm looking for, players will get into my team. Lee knows exactly what I want to do and I can confidently say that he is having a right good go at doing it.
"His training this week has been as good as anything I have seen from him, even when I had him at Plymouth. That bodes well."
