Souths pack offers toughest test: Watmough Manly star Anthony Watmough says he is in awe of the size and power of the South Sydney pack as the two NRL heavyweights prepare to face off on Friday night. The Sea Eagles and the Rabbitohs sit on the second rung of the ladder after six rounds behind undefeated premiers Melbourne and Watmough said the Brookvale Oval clash will be a big test of both side's title credentials. Souths' success has been built on the back of a dominant forward pack and Kangaroos back-rower Watmough said the Sea Eagles were determined to match them. I don't think I have seen a bigger team. There should be a weight salary cap because they are massive," Watmough said on Monday. I had a little think over the weekend about how they will be trying to run over me. I will just have to put the little frame in front and see how I go. I don't think you can enjoy it too much. It's a good challenge. Our young guys will certainly get a baptism of fire this weekend. They are a big pack so they are definitely going to test us. We like to pride ourselves on our forward play and we have some big boppers who can match them. If we go with them and try to play our normal game we will go a long way to winning the game. We haven't played easy beats this year but we haven't played the top teams in the competition and I think the Rabbitohs are one of those. Rabbitohs youngster George Burgess has emerged as one of the form forwards in the early rounds of 2013 and Watmough said Manly would have to be wary of his powerful runs. I have been watching him play and watching him run through people. He just tramples them, and you just have to get in front of them, there's no other way," Watmough said. It's a collision sport and we love the collision at this club, but it's going to be a bit different this week. We just have to get in front of them. We just have to do it. We have to stop them. Manly say they won't rush representative back-rower Glenn Stewart's return for the game. Winger David Williams has recovered from a back injury and will play.
