Arsenal's Invincibles will go down as one of the Premier League's greatest-ever sides, but for Emmanuel Petit, Jurgen Klopp's current Liverpool crop are 'more impressive'.
Arsene Wenger's team for the 2003-04 campaign pulled off the incredible feat of going a full season unbeaten on their way to win the title.
The opinion is made even more controversial given that it's coming from a former Gunner, who played alongside many of those that would go on to win the Premier League without losing a game.
However, Petit insists that while he still respects his former team-mates achievements, there is just 'something special' about Liverpool.
