Aston Villa boss Paul Lambert is keen to strengthen his young squad but not at the expense of the club's financial stability.
Lambert, whose Villa side are in a relegation scrap, said: "I understand the finances of it. The club cannot go into major debt. It's got to watch itself.
"It's something I'll meet head-on. I don't know how much, off the top of my head, the chairman (Randy Lerner) has put into the club. I'm pretty sure it's not light.
"I've spoken to him. There are one or two lads there that we will try to get. A lot is dictated by finance. We need a bit of strength in the middle of the pitch.
"Prices in January can be so inflated that you can pay through the nose for someone, and it's a guy you maybe don't want at the club.
"We have to build this club and not let it go back to what has happened before."
