Leeds United have already made signings in the January transfer window.
The Championship outfit are looking for players in order to strengthen their squad and push for the playoffs.
The Whites have already made two signings this month. Liam Bridcutt has extended his loan spell from Sunderland until the end of the season, while Mustapha Carayol has switched from Middlesbrough for the rest of the 2015-16 campaign.
Evans has suggested that he is looking for more players, but he has made it clear that he will not pay over the top for them.
“You have to be patient and you have to get value of money,” the Scot told The Yorkshire Evening Post. “We come up with our intended targets and we attach to that what we believe the value would be.
“The minute it exceeds those values, you have to be strong enough to walk away. This club has been guilty in the past of overpaying.”
Leeds are 13th in the Championship table at the moment with 32 points from 25 matches. The West Yorkshire outfit are nine points behind Ipswich Town, who are currently sixth in the standings and occupy the final playoff spot.
The Whites have an outside chance of making the playoffs, and perhaps with one or two more signings they will be able to launch a strong challenge.
