Aldridge was impressed by Christian Benteke's cameo performance against Chelsea.
Benteke signed for the Reds for £32.5 million in the summer - as reported by the BBC - in order to address the side's lack of cutting edge in the final third, and Saturday's 3-1 win over Chelsea saw him score his second goal in as many substitute appearances.
The Belgian's introduction has been widely acknowledged as being key to Liverpool's victory, given his involvement in Philippe Coutinho's second goal as well as finding the net himself.
Aldridge wrote in his Liverpool Echo column that Chelsea simply couldn't handle the 24-year-old, saying: "It was clear from the moment Christian Benteke came on that Chelsea couldn’t handle him.
"And encouragingly for Liverpool, it was also clear that they are starting to work out how to play to the big man’s strengths.
"We’ve paid £32m for this lad; we simply have to use him properly. That means balls he can attack, and runners off him. Look at the second and third goals Saturday - midfield runners.
"Benteke’s got four goals now, despite having not had much playing time. If we give him the service, he will score goals."
Jurgen Klopp has been unable to use Benteke from the start of a game yet because of a hamstring injury he was carrying when the German arrived, shortly followed by a slight knee problem. Given the striker options currently at Klopp's disposal, he will inevitably want to use Benteke from the start in the coming weeks.
Certainly, Benteke's presence and strength caused Chelsea a lot of problems, as well as his aerial ability, but his calmness and composure probably doesn't get talked about enough, certainly when you look at the manner in which he took his goal on Saturday.
Liverpool have yet to see him in full flight, and will hope that he gets fitness under his belt in the coming weeks so they can really see what he is capable of, as there looks to be more to the player than his presence. His pace against any defence trying to push out can also be a useful asset.
