Mike Mulvey's patience has run out with his Central Coast side, after they claimed an unwanted record with their 2-0 defeat away to Wellington Phoenix.
The Mariners have posted the worst start to an A-League season, with just two points from the opening eight rounds.
Their overall record stands at just one win in their last 26 league games, and Mulvey feels it's time to shake things up with his selections.
Mulvey admits the Gosford club are "way off the pace at the moment", and are being held back by fear.
The Mariners finished bottom of the table last season and risk being cast adrift by the other teams before the turn of the year.
They suffered a sixth consecutive defeat in Wellington, which could be the catalyst to a turn to youth.
Mulvey said: "We do have a plan but we need to now give some of our young lads a bit of a chance and next week [against Newcastle Jets] is a good opportunity to do that."
The Mariners coach said the Mariners were continuing to shoot themselves in the foot, conceding first-half goals against the Phoenix to Louis Fenton and Sarpreet Singh.
"We need to be on the ball, we need to be there in key moments and we weren't today," said Mulvey, who returned as an A-League coach in the off-season four years after being sacked by Brisbane Roar.
"We've got to give the young lads a go," he added. "We had a couple of lads come on towards the end of the game, Josh Macdonald and Mario Shabow and they deserve game time now.
"They don't have any fear; some lads unfortunately get a little bit gripped by fear."
Central Coast are 5/2 to win their next game against Newcastle, who are 1/1 with the draw 13/5.
