There may be some tension in this match as a number of Waratahs players have left the Brumbies and now play for the Waratahs so the Brumbies will be keen to give them a home "warm welcome"
Both teams have made minimal changes to their line ups and while the Brumbies have shown better form they have traveled from west to east so their performance will more than likely suffer from the travel.
The Brumbies seem determined bring back the old days and to make Canberra the fortress it once was.
