A CROSS-CODE war of words has erupted, with rugby league legends laughing off the Brisbane Roar's claim to a new Australian sporting record.

Ange Postecoglou's men officially made history on Saturday night with their 4-0 triumph over Perth giving them a string of 36 unbeaten A-League matches unbeaten.

The win saw the Roar surpass NSW rugby league outfit Easts' 35-game unbeaten record, set in 1937, prompting a social media war over which landmark was more valid.

League Immortal Arthur Beetson, a former Easts coach and playing member of the club's famous 19-game winning streak in 1975, says the fact that the Roar has drawn 13 matches in its unbeaten run leaves the debate open.

"They have had a lot of draws in there,'' Beetson told mX.

"Easts had a couple of draws (in 1937) but there are a lot of draws (in soccer), even in Europe a lot of those (unbeaten) records have a lot of draws.

"But they have scored in every game, which is good because a lot of soccer can be negative.''

Former NRL great Matthew Johns today took aim at the standard of the A-League competition, comparing Brisbane's streak to Matthew Hayden's Australian record score of 380 not out, set against Test cricket minnows Zimbabwe in 2003.

"That's a little hollow isn't it?,'' Johns told Triple M.

"It's a little bit like when Matthew Hayden broke Sir Donald Bradman's record….but he did it against Zimbabwe.''

Many Sydney soccer fans also questioned the significance of the Roar's efforts, with more than 50 per cent of voters on a Triple M poll claiming the run is not "worth celebrating''.
