Aldridge likes that Rodgers has made changes to the team and the style in a bid to get their season back on track - but feels another forward should be brought in as soon as possible.
In the last couple of games, Liverpool have gone to a more 'back to basics' style of play as they bid to get some points on the board and kick-start their season.
The results so far have been a 2-2 draw against Ludogorets in the Champions League which kept qualification for the knockout stages of the competition in their own hands, and a late 1-0 win over Stoke City at Anfield in the Premier League at the weekend.
In his Liverpool Echo column, Aldridge said: "The manager has come in for a plenty of stick recently but he deserves credit for what he has done to try and turn Liverpool’s form around. He has shown that he is not set in his ways, so to speak.
"Liverpool have had stubborn managers in the past but Brendan proved that he can move away from his principles and I salute him for that."
The former striker also urged Rodgers to enter the transfer market in January to bring in another forward, and called for the standard set by the midfielders on Saturday to be continued as the Reds try and become more solid at the back.
As it stands Rickie Lambert is the man leading the attack and is being relied upon to provide for the Reds in front of goal. Sturridge has had terrible luck with injuries this season in particular, but his injury record as a whole suggests that there is a need for a new forward in the January window. Combine that with Mario Balotelli not really finding any form, and struggling to adapt to the Reds' system, it strengthens the case even further.
Aldridge added: "It has become even clearer in my mind that the Reds need to bolster their attack in January with a new signing.
"There just aren’t enough goals in the team but we can edge games by playing Steven Gerrard in behind Lambert and using the pace and creativity of Raheem Sterling and Adam Lallana off them.
"Liverpool have also got to defend staunchly. And behind them Lucas, Jordan Henderson and Joe Allen all battled for everything on Saturday and that has to be the standard from now on.
"We are not going to win games 3-0 or 4-0 at the moment as we did last season, we haven’t got the players to do that so Liverpool just need to grind out a series of wins between now and January.
"And in January, as I say, we need to do something in the transfer market and if that means losing a player to make way for another, then so be it."
