#2 Liverpool (2019-present) - 44 matches
Following an extraordinary performance at the UEFA Champions League last season, it was expected that Liverpool would kick off the current Premier League season with a bang, but nobody could've predicted just how strong this squad would turn out to be.
As of now, Liverpool's undefeated streak stands at 44 games and of the 27 games played this season, they've only dropped points once at Manchester United.
If not for their only loss in the 2018-19 campaign to eventual champions Manchester City, they would've long surpassed The Incredibles' tally of 49 games and would be on a 66-game unbeaten streak.
Their current run got underway on 12 January 2019 and it's been more than a year now that they have gone unbeaten in the league and what is even more impressive is that they haven't tasted defeat at Anfield since April 2017.
It is said that all good things must come to an end and naturally, this incredible streak will also come to an end, but one can only hope that the Reds manage to become the first team in history to remain undefeated for 50 games by then.
