Liverpool are on the verge of joining an unbeaten elite group in the history of the Premier League if they can avoid defeat in their next match.
The Reds have been phenomenal this season and demonstrated that once again last time out when they floored defending champions Manchester City 3-1 at Anfield.
Jurgen Klopp's men will become the only fifth team to go 30 matches unbeaten if they avoid defeat in their next match against Crystal Palace.
Liverpool are 29 league matches without defeat, a run going back to 3 January 2019, when they were beaten by Manchester City.

The Invincibles is the tag Arsene Wenger's men got after going a whole season unbeaten in their title-winning campaign shortly after leaving Highbury.
