The Reds shelled out around £80m in the summer, with big-money outlays for the likes of Roberto Firmino (£29m) and Christian Benteke (£32m), but seven points from their first three games perhaps masked a lack of creative spark in the final third of Rodgers' side - Philippe Coutinho apart.
However, the Reds have struggled in their last two games either side of the international break, and a porous defence have shipped six goals in respective 3-0 and 3-1 reverses to West Ham and Manchester United.
As disappointing as the home defeat to West Ham was, it was the timid and insipid performance at Old Trafford that has really irritated supporters of the five-time European Cup winners.
A midfield diamond of Lucas Leiva, Emre Can, James Milner and Firmino did little to retain possession away to their fiercest rivals, and Benteke was left isolated for long periods as the lone striker, with Danny Ings forced to operate in a wide area to combat the threat down the right of Louis van Gaal's side.
Benteke has performed admirably since his big-money move from Aston Villa and hs ovrhead kick against United is already a contender for goal of the season, but too often the Belgium international was forced to feed off scraps and aimless punts in his general direction. At £32m, the striker deserves better than that from his teammates.
Rodgers professed to inflict "death by football" upon his arrival at Anfield in 2012. It was a nod to his preferred playing style of a possession-based team who moved the ball along the carousel to eventually beat opponents into submission.
However, that ideal was a world away from what was served up at Old Trafford, and Aldridge has hit the nail on the head in his weekly Liverpool Echo column.
The former Republic of Ireland striker wrote: "It’s been another miserable weekend, filled with unhappy Liverpool supporters. There are lots of angry Reds at present, Reds looking to vent and to express their frustrations. Liverpool fans are right to be angry, their team has lost its identity
"I don’t blame them. It’s not good at the moment, it really isn’t. Performances are poor, and the last two results have been awful There’s pressure on the manager, make no mistake.
"He needs to find a solution to his side’s problems. Fans are starting to get on his back, some are even calling for blood, but everyone knows that we have to improve fast."
Rodgers is likely ring the changes when his charges visit Bordeaux in the Europa League on Thursday.
