The Reds strengthened their midfield options in the summer transfer window following the disappointment of a 3-1 loss to Real Madrid in the Champions League final.
Liverpool FC signed Brazil international Fabinho in a £39m deal from Ligue 1 side AS Monaco after an impressive three seasons at the Principality.
Jurgen Klopp welcomed Guinea star Naby Keita to his squad in July after Liverpool FC agreed a £48m fee with Bunesliga side RB Leipzig back in 2017.
While Keita has started four of Liverpool FC’s five Premier League games so far, Fabinho is still waiting to make his first appearance in Klopp’s XI.
Indeed, Milner’s incredible form has kept Fabhino and Liverpool FC captain Jordan Henderson on the bench.
The versatile midfielder netted Liverpool FC’s second goal in a 3-2 win over Paris Saint-Germain on Tuesday night, as well as teeing up Roberto Firmino for his late winner.
He came off the bench on Saturday to help the Reds ease to a 3-0 win over Southampton at Anfield.
Former Liverpool FC defender Warnock was full of praise for Milner after his influential performance.
“He is brilliant,” Warnock told BBC Radio 5 Live. “Milner sees the signing of Fabinho and Kieta as a challenge. He will set the standard and see if they can keep up with him.
“He won’t give up his shirt without a fight. He has been Liverpool’s standout performer this season. His tenaciousness and desire to win. Sometimes it wanes when you get older. He is just getting hungrier and hungrier.”
Liverpool FC signed Milner in a free transfer from Manchester City in the 2015 summer transfer window under Brendan Rodgers.
Milner was used as a left-back throughout the 2016-17 season before he was switched back to his preferred role in the middle of the park.
