Despite this latest set-back, McManus insists Turnbull will become a Celtic player this summer.

He wrote on Twitter: "David Turnbull has a small problem with his knee that requires an op (tidy up). Be out for 10-12 weeks. That’s it. Some of the s***e I have heard about him on here is poor & embarrassing. Hurtful rumours about the kid. The deal will 100% still go through."
