Roberto Firmino missed Liverpool training on Friday afternoon, just 48 hours before Liverpool take on Manchester City at the Etihad.
The Reds are looking to achieve a famous win against their Premier League title rivals on Sunday afternoon. Pep Guardiola's side are currently one-point ahead of Jurgen Klopp's team at the top of the table, with no other title contenders in sight.
Firmino was not spotted at Liverpool's AXA Training Centre at Kirkby on Friday afternoon, although Klopp is still hoping to have a full-strength squad at his disposal for the big game. Many are billing it as this season's defining fixture.
