Millwall manager Joe Edwards says he won't hold Allan Campbell against his will.
The midfielder is on-loan at Millwall from Luton.
Speaking to the Southwark News, Edwards said: “I can't tell you anything in relation to what Luton have or haven't said because I haven't been told anything myself about Luton. Allan's obviously a player that has left his parent club on loan to get game time and isn't getting much of it. So if Allan's got a frustration with a lack of game time, I completely understand that.
“It's not easy. It's obviously an area of the pitch for us in midfield and particularly in this recent period I've liked what George Honeyman and Billy Mitchell had been doing together and before that, George Saville had been a big player for us.
"If there's a frustration from Allan's point of view we need to have a conversation. And if there's a solution that works for everyone, then that's something I'm more than happy to participate in but at the moment I've not been told anything to be honest."
