Liverpool's astonishing form this season has left all their rivals chasing shadows in the Premier League.

An incredible 20 wins from 21 games has seen Jurgen Klopp's side establish a 14 point lead from last season's champions Manchester City before Saturday's games.

They have dropped just two points all season, and that came against Manchester United when Adam Lallana's late goal rescued a draw at Old Trafford.

Liverpool are up against their arch enemies again on Sunday. Here's what happened in October in that previous meeting.
