Oxford chairman Ian Lenagan insists he will only judge manager Chris Wilder when he has a fully-fit squad available.
Some fans have called for Wilder to be sacked after six successive league defeats but his side has been ravaged by injury so far this season.
But Lenagan has stood by the 45-year-old and says he will not be forced into any rash decisions.
"I am strongly of the opinion that you judge a manager when he has had the opportunity to have his strongest squad on the field and not before," he told BBC Radio Oxford.
"My job as chairman is to stay calm during that storm and make considered and balanced judgements on behalf of Oxford United.
"My experience tells me that in many cases reactive judgements that the fans want us to make can often lead to more destructive results."
