Former Cronulla captain Brett Kimmorley says the Sharks are struggling and will have a mountain to climb this weekend against the in-form Sydney Roosters.

“Three losses in a row, haven’t won over the last four weeks, Sam Tagataese will not play until the Grand Final qualifier and that means they lose some physicality of a big frontrower going forward – but they do get Paul Gallen back” Kimmorley said on espn.com.au.

“I think they’re struggling, I think there is a little bit of nervousness starting to creep into the belief of the Sharks fans and possibly the Sharks players and they’re playing a red-hot Roosters side this weekend.”
