Fashion Sakala has been identified as the major danger to Celtic in the Viaplay Cup Final at the end of this month.
Former Hoops star Andy Walker reckons his old club will have to learn their lessons from the last time they faced Rangers on January 2 when the Zambian attacker was a real thorn in their side and gave Josip Juranovic a really torrid time.
Sakala has been re-energised since the arrival of Michael Beale and really stretched Celtic in that match, setting up Ryan Kent for an equaliser and then winning a penalty converted by James Tavernier although Kyogo Furuhashi spoiled his day with a crucial late equaliser.
