Speaking at midweek training, Carver said: "One thing is for sure, I am going to be making changes to the side. I'm not going to say what those changes are, but there will be changes in personnel. We've changed a few things and done a lot of work defensively this week.
"The guys have worked on the back four, rotating the central defenders, and they've worked on being more solid. Hopefully we will see an improvement."
