Birmingham confirmed on Friday that the Reds are holding talks over signing goalkeeper Jack Butland, while the Anfield outfit are close to securing Chelsea forward Daniel Sturridge and Blackpool winger Tom Ince.
And the Liverpool manager has confirmed he will be making signings in the upcoming window as he looks to improve on a disappointing start to the campaign.
"We'll be able to make some additions in January to help the group," Rodgers told reporters.

"We're hoping we'll be able to do something pretty early on in January – and then we'll see what else January can bring.
"But the main review will take place in the summer, and it is clear we need that bit of experience up at the top end of the field.
"The best and most important period will be between now and the end of the season, when we can look at what needs to be done, in terms of progressing the club further, and then go again."
Rodgers also revealed that Uruguayan forward Luis Suarez will be fit for Sunday's clash with QPR, despite picking up an ankle injury during the Boxing Day defeat at Stoke.
"Luis will be fine," he said. "He's a real robust player and is very rarely in the treatment room.
"He's been playing with a bad ankle for a couple of weeks and took a heavy knock the other night, but he's fine."
