Leading defence consultant David Wessels has joined the Western Force for the 2013 Super Rugby season.
Wessels has proved his success previously at the Stormers and the Brumbies where he held the same position.
During his time at the Stormers (2008-9) he helped establish a tight defensive culture, while the Brumbies last season conceded the fewest points in the Australian conference and the second least in the Super Rugby competition.
Head coach Michael Foley says Wessel's appointment continues the Force's focus on quality recruitment.
"When we were assembling our coaching staff, we placed an emphasis on engaging experts with a record in getting results - and this certainly extends to David," he told the club's official site.
"David has proved excellent results through his work with the Stormers and Brumbies. The Stormers have been regarded as one of the benchmarck defensive units over a number of years while the Brumbies' success last season was the back of a very tight defence.
"While we want to be playing dynamic and up-tempo rugby with the ball, we need to have complete faith in our defensive systems, which we believe is something David can provide."
Wessels joins Foley on an the Western Force coaching panel that already features former Bath coach Steve Meehan, two-time Rugby World Cup-winning strategist Phillip 'Chook' Fowler and former Wallaby front-rower Nick Stiles.
