South Sydney coach Michael Maguire admits the Rabbitohs must get their shop in order to return to the NRL winners' list.
Maguire said Souths' defence, discipline and ball control were all substandard in last weekend's 25-16 loss to Wests Tigers.
He said anything less than a vastly improved performance would result in another defeat against Canberra at ANZ Stadium tomorrow. Such a result would mean three consecutive losses for Maguire for the first time since replacing John Lang as coach in 2012.
"We haven't had the two results we would have liked the last two weeks and we're working hard and doing all the preparation to get the result we're after," Maguire said yesterday. "We've put our heads down and we're looking at the things we judge as our standards and we want to make sure we're hitting those this week.
"There were a lot of areas of our game that we went away from, but I thought the defence was the biggest thing that we lacked.
