South Sydney Rabbitohs say they aren't giving Sonny Bill Williams a second thought ahead of clash with Roosters Sam Burgess and the Rabbitohs are more than ready for the challenge of stopping the returning Sonny Bill Williams when they take on the Roosters on Thursday night. SONNY Bill Williams might give opposing players nightmares, but the Rabbitohs are barely giving him a second thought. With the Roosters-Rabbitohs season opener just three days away, Souths' own superstar second-rower, Sam Burgess, yesterday said there'd be been little talk about the Roosters' highest profile recruit. "To be honest, if Sonny wasn't playing I would still be excited, it doesn't make a difference to how I feel," the Englishman said. Burgess has made it known to South Sydney coach Michael Maguire that he wants to play on the Rabbitohs' left edge this year - and Roosters coach Trent Robinson has already stated he believes SBW is best suited to the right edge. That means big Sam and SBW will more than likely be eye-balling each other at some stage in Thursday's NRL season-opener. He is just another player in their team. We have been focusing on ourselves and getting our own performance right," Burgess said. I'm not sure if I'm going to start (on the left) but whoever is up against him is certainly going to have a challenge. He is a good athlete. We are certainly going to give him respect but we have got a job to do at the end of the day. Roosters recruit Luke O'Donnell, who like Williams makes his debut for the club on Thursday, said he expected the big Kiwi to feature. "He's trained like he's going to be playing," O'Donnell said. But we've all got a job to do so everyone's mind will be 100 per cent on playing well. Rabbitohs legend Mario Fenech said he was glad Burgess was wearing Bunnies colours. Asked if he would swap Burgess for SBW, Fenech said: "No. What I do like about Sam is this; To play rugby league at a high level you have got to have an element of mongrel in you.
