Rodgers revealed the board is putting a limit on spending this season.
"When I came into Swansea in the first year we had 12 players [come in] over the course of the season, six moved on. In the second season seven came in, nine others went the other way. Until you get that turnover of players, then you can't look at it as your team," he told liverpoolfc.com.
"I'm not so sure it will be in January, to be honest. This year the club wanted to balance the books and see where it was at.
"There was a big investment in the club and obviously a lot of players went out in the summer, and a few came in. We'll look to do some business in January to help and support the players that are here.
"That's where we're at as a football club. The owners trust me to grow it over time. Obviously as a manager you're always looking short-term because you've got to take care of the short-term, but eventually we'll get there."
