Former Broncos skipper Corey Parker has thrown down the gauntlet to superstar Reece Walsh, declaring the fullback ace "hasn't done anything yet" in the lead-up to Sunday's clash with the Roosters in Las Vegas.
Parker is a huge Walsh fan but believes the try-scoring ace still needs to prove himself at the elite level – starting with the historic clash against the Roosters.
"There is no doubt that Reece has lit up the NRL, but there are still some errors in his game at times," Parker told Wide World of Sports.

"I've had a lot to do with him since he was 15 and always knew he was a special talent.
"But really, he is still a kid and now has a huge target on his back.
"He's got a Harry Styles-like following, but to me he still hasn't done anything yet compared to what he is capable of."

Parker played 347 matches for the Broncos between 2001-2016. He was skipper in 2016 – the 16th and final final season of his career.
"I'm excited to see what he has learned from last year, particularly the grand final, which was so painful for all the Broncos," Parker said.
"On top of that, they have lost some real quality players and it's up to the young guys in the Broncos team like Reece to step up and fill the void."
Parker won't be in Las Vegas for the weekend extravaganza but will still play his part in the historic double header.
"I'm hosting a 'Viva non-Vegas' party at Sydney's Star City for all those people who couldn't make the trip over," he said.
"It's free entry and should be a great afternoon's entertainment watching the games on the casino's big screens.
"There will be other personalities there mingling with the fans and I can't wait."
