One of the areas where Brendan Rodgers needs to bolster in January is the central defence. Adding depth in the attacking department is also key, but Rodgers can no longer ignore the importance of adding a quality centre-back to the squad.
Dedryck Boyata has not signed a contract extension at Parkhead, and Celtic could lose him for nothing in the summer. So, the Bhoys could sell him now, and reinvest in the squad.
One player who is looking to continue at Celtic Park, however, is Filip Benkovic. The 21-year-old joined the Bhoys in the summer transfer window on loan from Leicester City and has been brilliant for the club.
