Lallana's late winner against Norwich City saw him score his first Premier League goal for eight months, and Aldridge was pleased with the player's performance from the bench.
Liverpool legend John Aldridge has said Saturday's cameo performance was the best Adam Lallana has produced for the Reds, and has outlined what should be expected from the 27-year-old over the course of a season.
Aldridge feels that Lallana should be hitting double figures in goals after ending a goal drought in the Premier League which spanned eight months by hitting the winner against Norwich City in the dramatic 5-4 win at Carrow Road.
That adds to Lallana's two goals from the Europa League so far this season, while he has five assists to his name so far this season.
The former Liverpool striker wrote in his Liverpool Echo column: "If he’s honest with himself, Adam Lallana will know he’s underperformed since he came to Liverpool, even taking injuries into account.
"But that was the best half an hour he’s played for Liverpool by an absolute mile.
"He changed the game when he came on, was busy, effective, put in a great ball for Firmino’s goal and finished really well at the end.
"That is what Adam Lallana is about, we’ve seen it for Southampton and England."
The change of shape that went along with Lallana's introduction seemed to suit him well as he operated from a more central role and ran the channels well to create space for those around him - while his goal was a case of being in the right place at the right time to strike for the Reds.
The context of which he played made the performance that bit more impressive as he was a doubt for the game because of a muscular problem.
After his goal, Lallana will no doubt want to kick on and find the net more regularly, and the supporters will be hoping for similar fortunes.
