Arsenal's Invincibles were one of the great teams of the Premier League. But for Emmanuel Petit, this current Liverpool squad under Jurgen Klopp "have something special" - something that makes them "different" to any other top side in English history.
Arsene Wenger's Arsenal went an entire Premier League season unbeaten in 2004, but drew 12 games as they accrued 90 points to win the title.
Klopp's Liverpool were beaten by Watford this campaign, but have won 27 of their 29 fixtures, and were on course to hit the 100-point mark before coronavirus brought world football to a standstill.
Petit played alongside some of the Arsenal players who went on to go a season undefeated during his three years in north London from 1997 to 2000.
