Leeds United drew 0-0 with Charlton Athletic in their most recent fixture.
Evans was eager to get another striker in the pitch at The Valley, after watching his side dominate for much of the contest, but he was told to be cautious.
Leeds’ dominance in the fixture was obvious, and the coaching staff at the club felt that by changing the team's shape it could have had a detrimental impact on their performance.
“I was desperate to bring Antenucci on, and get another striker on, but I think the staff were right,” Evans said.
“The staff’s words to me were to be cautious, as we were so dominant and we were making so many chances.
“I know you say that if you bring Mirco in, does he get one, but it would have changed the shape.”
Even without Antenucci, Leeds managed to carve out chance after chance at The Valley, but they could not put the finishing touches on their excellent play.
The Whites spurned a number of golden opportunities, with Tom Adeyemi arguably the most guilty.
Adeyemi burst through late on, but he scuffed his shot wide from six yards to cap off a frustrating afternoon for the Whites.
Leeds had 18 shots in the match, but they only hit the target with three of their efforts.
The draw leaves the Whites in 18th place in the Championship table, but they have only lost two of their last six matches.
