The Anfield boss was left short of options when he lost Jose Enrique to a hamstring injury in January and hopes to provide cover for before the summer transfer window shuts.
Rodgers lost first-choice option Jose Enrique to a hamstring injury in January and had to use Glen Johnson and Andre Wisdom in the position instead, and the former Swansea boss feels it is important to bolster his squad and provide cover for the Spaniard before the transfer window shuts.
"There are obviously certain areas of the squad where we're a bit thinner than others," Rodgers said. "We probably need a bit more support - that extra bit of quality - at the top end of the field and that's something we'll look out for.
"That'll be mixed with needing cover in the left back position - that's something we're looking at. It's not really about numbers, it's about quality.
"If we can do that over the next number of weeks we'll be happy."
The Reds recently made an approach for Chelsea and England left back Ryan Bertrand, who is Ashley Cole’s understudy at Stamford Bridge, but the player insisted he wanted to remain put and become the club's No. 1 left back over time.
