talkSPORT Drive presenter Adrian Durham caused a stir when he claimed Arsenal's unbeaten Premier League champions of 2003-04 were "overrated" (see the video below).
He backed up his argument by claiming, contrary to the nickname given to that team, the Gunners weren't truly invincible having lost six times in cup competitions, including a Champions League elimination at home to Chelsea.
By contrast, Manchester United's 1998-99 treble winners lost four games in all competitions (three in the Premier League, one in the League Cup), winning the title, Champions League and FA Cup.
