Tom Rogic, Moussa Dembele and Scott Sinclair were all on target for Celtic as they dispatched Motherwell 5-0 in the last-16 game of the Betfred Cup.
Rogic and Dembele both scored braces for Brendan Rodgers' Bhoys while Dembele's fellow summer signing Sinclair continued his goal scoring run with a fine second-half strike.
Australian midfielder Rogic opened the scoring for the Glasgow giants in the 20th minute before Dembele doubled the lead from the penalty spot 14 minutes later.
All three goalscorers found the net in the second half of the game as Celtic moved through to the quarter-finals where they will meet Alloa Athletic on September 21.
