The White influence should have the Brumbies among Australia's leading challengers for the Super Rugby title.

Made the play-offs last season with a transitional team after the loss of legends such as retired Victor Matfield and transferred Bakkies Botha and Fourie du Preez, but were found wanting away to Crusaders.

The lure of the euro will further deplete the Bulls' stocks at the end of the 2013 campaign with fly-half Morne Steyn and lock Juandre Kruger off to France on lucrative contracts.

Much is expected of centre Jan Serfontein, captain of the 2012 Junior World Cup-winning team while scrum-half Francois Hougaard needs to recapture the form shown as an impact player at the 2011 Rugby World Cup.

While a fourth title this season mightappear to be beyond the Bulls, they will hope Steyn regains the world-class goal-kicking form that deserted him last year, and a top-six finish and a place in the play-offs is a realistic expectation.

Often the most entertaining South African side as they favour keeping the ball in hand and have elusive runners, but a sometimes non-existent defence means they consistently finish in the bottom half of the table.

They boast a superb goal-kicker in young Springbok Johan Goosen, who was the leading points scorer in 2012 until a mid-season shoulder injury sidelined him for the rest of the competition.

Giant Ghana-born left-wing Raymond Rhule is set to make his debut after an outstanding first season in the domestic Currie Cup, scoring numerous tries through pace and power.
