Jose Mourinho and John Terry have claimed Chelsea's 2004-05 Premier League-winning team were better than Arsenal's famous Invincibles side.
The Blues romped to the top flight title 20 years ago following a remarkable season that saw them rack up 95 points and concede just 15 times, an English league record.
Mourinho had replaced Claudio Ranieri as manager the previous summer, and his side finished 12 points clear of Arsenal. Their only defeat came against Man City in October 2004.
The Gunners had been the reigning champions, with Arsene Wenger's men picking up 90 points during their memorable 2003-04 campaign having become the only top flight side to go undefeated.
