Corey Parker believes the Des Hasler "experiment" at the Titans is "not working".
The former Queensland representative's comments come amid increasing pressure on the veteran coach.
Gold Coast sit outright last on the NRL ladder after Round 16, with Sunday evening's loss to the Eels marking their 10th defeat of the season.
The 64-year-old joined the club as head coach in 2024, leading them to a 14th-place finish.

With the Titans failing to show consistent signs of improvement this season, Hasler's future is under the microscope.
Parker notes how the club sacked previous coach Justin Holbrook when they were sitting ninth at the same stage of the season in 2023.
"Let’s try and boil this down. I like Des Hasler, I do, but I'm sorry, the experiment is not working," Parked said on SEN.
"Justin Holbrook was sacked, and he was sitting ninth in the competition at that point in time, with a host of wins under his belt and a tight comp.
"The Gold Coast Titans at the moment are a basket case, and that is being nice."

Despite being contracted until the end of 2026, it was reported in May that Hasler could find himself out of a job if results don't improve this year.
According to News Corp journalist Michael Carayannis, the veteran coach has a top-eight clause in his contract.
If the Titans fail to reach the finals this season, the club would be "under no obligation" to keep Hasler.
Hasler dismissed the idea of a potential early exit in Sunday's post-match press conference.
"They're just whispers, mate," he said.
"It's just rumour, innuendo."
Parker feels that the constant discussion around Hasler's job is worrying.
"We heard from the board not so long ago saying his job's safe, and normally when that happens, you're under enormous amounts of pressure, and you're out the door," he added.
"The roster could probably do a little overhaul from different points – there could be a few different things that are unfolding there, but at the minute, they are in a world of hurt."
