Crewe boss Dario Gradi accepted the criticism voiced by the Gresty Road faithful after his side went down 2-1 against Morecambe.
First-half goals from Jim Bentley and Phil Jevons earned the Shrimps their first win on the road this season and dragged Crewe, who pulled one back through substitute Steven Schumacher, to within six points of the drop zone.
"The fans were booing at the end and they have every right to voice their opinion. I have no problem with that," said Gradi.
"If I am not wanted I will be told but I want to do this job and believe there is something to work on here.
"I thought we played some good stuff in the second half but we didn't really have much cutting edge and don't really have a proven goalscorer.
"Conceding at corners and set-pieces is a problem and we need someone who can head the ball out of the box. If I can, I will bring someone in but I think the boys showed in the second half that what we have already isn't beyond hope."
