Rugby league legend Paul Gallen has blasted the Sydney Roosters labelling their discipline as “horrendous”.

Writing for the Wide World of Sports website, the former NSW Blues skipper also questioned veteran half Luke Keary’s form after coach Trent Robinson dropped his young counterpart Sam Walker a few weeks ago.

“For me, their discipline is horrendous, it’s really bad. By discipline I don’t mean just penalties, I’m talking about things like completion rates as well,” Gallen wrote.

“They’re really letting themselves down at crucial moments of the game.

“They’ve only scored 153 points this season, which is an average of 17 per game. That’s a concern, it’s the second worst in the competition. You won’t win a heap of games by scoring 17 points, regardless of how good your defence is.

“Only the Wests Tigers have scored fewer points this year than the Roosters, and we know where the Tigers are on the ladder.

“Everyone knows how important the spine is to each team, it’s crucial. You need a good spine and a couple of good front rowers, obviously. Their spine has been shuffled around, and Luke Keary probably isn’t doing what he’s done in the past.”
