Gary Simpson questioned his side's style after Macclesfield were dumped out of the Johnstone's Paint Trophy by Crewe.
Teenager Max Clayton struck the crucial goal for the Railwaymen in the 75th minute to settle a hard-fought 1-0 loss and Simpson was left unhappy with how ineffective his side's passing game was.
He said: "Neither team worked the opposing keeper hard enough.
"And that was the problem with our performance. I don't like passing it around too much without being effective.
"As the game went on I thought one goal would be enough to win it.
"We didn't have the enthusiasm to get into the box with enough desire to trouble them. A few of the lads were off colour and we need to step it up."
