Now, though, he has become a first-choice midfielder for Jürgen Klopp and has produced three goals and assists already this season. Still, he acknowledged the difficulty of adjusting to life at Liverpool, and credited Sadio Mané for making the jump from Southampton look easy.
"Comparing it to myself, when I came in, it probably took me a bit more time to settle," Lallana said (via the Mirror). "So credit to him, because it's never easy coming to a big club."
"I sit next to Sadio in the dressing room and I can't believe how quickly he's got into his rhythm," he added. "He's the Sadio we played against last season who was so good against us - especially at St Mary's."
It was once popular to mock the Reds for their big money acquisitions from Southampton, but now those players make up four starters on a unit poised to push for the top four. And while it took the likes of Lallana and Dejan Lovren time to grow into the team, Sadio Mané has made himself a weapon right away.
