IAN Holloway has revealed that he only wants to sign players on loan who could have a long-term future at Millwall.
The Lions boss will be able to strengthen his squad again from Friday, when the window for emergency loan deals opens to clubs in the Football League.
Crystal Palace midfielder Jonny Williams is reportedly available on a short-term basis, and Holloway, during his time as Eagles boss, described the 20-year-old as "a David Silva type."
But Holloway has effectively ruled out a move for Williams, saying that he has no interest in developing a player who does not have a future at The Den.
"It would depend on the cost," he said. "Jonny is a good little player but I don't know where he would fit in here.
"I need to get long-term things for us and borrowing young players can be very dangerous.
"Yes, Simeon Jackson and DJ Campbell are both here on short-term deals, but they're worth goals this season so that's slightly different.
"What I have never liked doing is improving other clubs' players only for them to go back at the end of their loan.
"Shaun Williams and Ed Upson are good signings for us because I can mould them.
"If there is someone out there in the loan market, who I think could be a Millwall player beyond the end of this season, I'll go for them.
"There's little point talking about Jonny Williams because he's going to be a Palace player for a very long time to come. He has just signed a new contract there."
Holloway has confirmed that some of his fringe players could leave The Den on loan.
"If anyone is here and I am not using them, and they want to go out on loan, then that won't be a problem," he said.
"Some of them aren't as fit as I need them to be, so I might loan a few out to get them fit. If that means promoting Jack Powell and Fred Onyedinma to the senior squad, I'll do it.
"I won't be looking to sign anyone before the Burnley game – I want to bed the new signings in first. I worked the players hard on Monday and Tuesday, and we were in again today."
