St George legend Johnny Raper has some simple instructions for the Dragons in their sudden-death semi-final against Manly tomorrow night - get the ball to Gaz.The rugby league immortal believes St George Illawarra have the overall strike power to upset the powerful Sea Eagles line-up at Brookvale Oval.But he says for the Dragons to do so, they need to utilise the sublime attacking skills of departing centre Mark Gasnier at every opportunity."When he wants the ball - then you give him the bloody ball. Don't muck around," Raper said. "When the backs call for the ball, get it there straight away - plus we've got very good finishers outside of Mark."Raper is a big fan of Gasnier and he says the dynamic ball-runner will leave a huge hole in the Dragons line-up when he departs for France."He's a very strong running back who can change a game," he said. "I think he's a very strong player and we'll undoubtedly miss him."He will be hard to replace, that's for sure, he'll be very hard to replace."While giving Gasnier opportunities to show-off his dazzling footwork and game-breaking ability was key, Raper said a team effort was required tomorrow night.He said the Dragons had the ability to win the semi-final but needed to pull together."They've got to play as a team and not as a bunch of individuals," he said. "They've been guilty of that at times this year - relying on certain players." The only way Gasnier could be slowed down tomorrow night, Raper said, was if he had a reoccurrence of his back injury."I expect him to go well - if he's fit he'll have a big game. But I don't think he'd play in this game if he wasn't fit, he's a pretty sensible footballer. I don't think he'd take the chance of letting his side down."
