Portsmouth manager Paul Cook is questioning his "unwavering loyalty" towards some of his players ahead of their League Two game at Mansfield.
Pompey were beaten 3-0 by Newport last weekend at Fratton Park, leaving them six points off automatic promotion.
Cook admits the loss has left him rethinking his selection policy.
"We need to shake off these inconsistencies as quickly as we can, which might mean changes in personnel," Cook told BBC Radio Solent.
"I've given unwavering loyalty to some players this season in my belief that the end product would be something that we all required.
"Last Saturday, that made me question my own beliefs in consistently picking all the same players."
Cook said his side's chances of automatic promotion were over following the defeat by Newport. But, his outlook has softened in the days since.
"With 10 games to go there's such a huge prize ahead," he said. "The disappointment from the defeats is what would more points have given us?
"The reality is we haven't got those points, but we've still got a huge amount to play for."
