The Reds were smashed 6-0 in 2007 by this yearâ€™s opponents Melbourne Victory and went home empty handed but Vidmar says the week leading in this time around has been much more relaxed.
"Two years ago it was a really hectic that week. There were a lot of things on, everyone was running around like mad people and trying to get things organised," he recalled.
"Certainly I feel this week has been really relaxed and not much fanfare and whether that's because we are going into the game massive underdogs, I don't know if that has anything to do with it.
"We went into that game with a few injury concerns and Matty Kemp was suspended as well, Greg Owens came in and played left back," he added.
"Going into this year, certainly Jambo (Scott Jamieson) has got an ankle problem but got through the game without any problems last week and no reoccurrence or swelling during the course of this week.
"We are probably as balanced and as relaxed as we possibly can be."
Vidmar also hopes to draw on the strength the players gained when going down in such a one-sided fashion in 2007.
"We are going to have a chat about all those things tomorrow. I will guarantee you there will be no repeats of 2007," he said.
