Out of the last five Super Rugby matches between the Waratahs and the Western Force the Waratahs have won four and the Force one.
The teams have played each other 9 times since the Western Force joined Super Rugby in 2006 and the Waratahs have won 9 and lost three times.
That translates to the Waratahs winning 67 % of their matches against the Western Force.
The average score when the Waratahs play the Force is Waratahs 21 Force 13.
This match will be played in Sydney where the teams have met each other 4 times.
In those four matches the Waratahs have won just once while the Force have won twice and drawn once.
Despite the Waratahs poor record against the Force in Sydney the Waratahs average score when they play the Force in Sydney is Waratahs 18 Western Force 17.
The Waratahs go into the match on the back of a confidence boosting victory over the Blues while the Force lost at home to the Cheetahs.
A week before their loss to the Cheetahs the Force beat the Reds so the Waratahs should not take them lightly.
At the time of writing the Force had not yet named their team for Sunday's match but no real surprises are expected.
This Match will be shown on TV in NZ, Aus, SA and a delayed broadcast in the UK on the Sky Sports Red Button/website.
