Crewe boss Steve Davis has said those who do not want to fight for the team can leave.
The club are bottom of League 1 and 12 points from safety after their 5th consecutive loss against Peterborough on Saturday.
"We want people who are prepared to fight for the shirt.
"If they're not, they can go. The one thing I want them to do is fight and for the first time this season there was a lack of that".
