South Sydney are just 80 minutes away from an NRL grand final appearance, but five-eighth John Sutton says it's vital they keep a lid on their emotions this week.
Sutton admits the Rabbitohs let the occasion of a rare finals appearance get to them in week one when they were drubbed by Melbourne.
Souths, who haven't won a comp in 41 years, rallied to book a preliminary final against minor premiers Canterbury with a 38-16 semi-final win over Canberra on Saturday.
But Sutton said on Sunday the Rabbitohs were fully aware they could not afford to let their emotions get to them as they did against Melbourne when they play the Bulldogs at ANZ Stadium where a crowd of around 70,000 is tipped.
"We probably just need to tone it down a bit." said Sutton.
Hopefully we get all our Souths fans out there behind us.
"I thought the emotions caught up with us a bit against Melbourne ... but I thought it was a good win last night and hopefully we can just jump on the back of that this week."
Sutton also admitted the Rabbitohs must improve in defence against Canterbury.
"They (Canberra) found a couple of cracks there. Hopefully we can just work harder and sort that stuff out and be good defensively next week."
"You just have to complete your sets and kick long and keep them down their end and don't give them too much ball. If we just keep completing, kick long ... we'll go well."
Canterbury and Souths have played twice this year for one win apiece.
