CELTIC will "reactivate" their interest in David Turnbull when the transfer window repoens in January as the Motherwell midfielder steps up his recovery to the first team.

Turnbull has since gone under the knife and is now expected to be back in the Fir Park first team by January, accoring to the Scottish Sun.
