Ferguson joined the Blues from Rangers in the summer.
Ferguson told the club’s official website: “I’m loving my football here.
“It’s the first time in a long time that I’m enjoying my football. I couldn’t have settled any better.”
He added: “I think everybody at the end of the season would take fourth bottom, but we’re progressing well under the management of the gaffer so hopefully come January we can add to the squad we’ve got.
“You can see what we’re trying to do on the park and the way we’re trying to play and I think if you ask any of the fans they would be happy with the progression. Hopefully we can take it on.”
