Jurgen Klopp has urged Liverpool's established players to step up their performances following the club's heavy investment in the summer transfer window.
With the Liverpool midfield having been especially strengthened this summer, the players who have been at Anfield prior to the summer will have seen their first-team places under threat.
"We talk about Naby Keita, that's good, he's new. The world is like that. When it's new it's fantastic," Klopp told the official club website. "What you already have [must say] 'yeah, I'm still here too'.
"James Milner made big steps in the last three years, that's the truth. I don't want to judge his career but it feels like it's the best moment of his career.
"Georginio Wijnaldum, no-one speaks about him. He can play the 'six' and the 'eight' in the way I don't know many players can. They don't talk about him.
"We only spoke about these three but Fabinho didn't play a minute so far and we expect big things from him. Adam Lallana, a long time injured. There's Xherdan Shaqiri too."
Liverpool return to action on Monday with a trip to Crystal Palace.
