The veteran midfielder’s performances have drawn the ire of the Anfield faithful, with many deeming him to be way past his peak.
Milner was dropped by Klopp following his performance against Manchester United in a 2-1 defeat on August 22.

Meanwhile, Alisson Becker starts in goal with a back four of Trent Alexander-Arnold, Joe Gomez, Virgil van Dijk and Andrew Robertson.

The Reds go with a front three of Mohamed Salah, Roberto Firmino and Luis Diaz, which means club-record signing Darwin Nunez settles for the bench.
