It was a comfortable evening in Glasgow for Ange Postecoglou's side as four goals saw sent St Mirren asunder at Parkhead.
Celtic looked strong from the get-go with Liel Abada smashing the ball home inside the box after Carl Starfelt and debutant Yuki Kobayashi went close from a corner. Postecoglou's men looked dominant before a lovely ball from Josip Juranovic landed at Kyogo's feet as he improvised with a stunning lob to beat Trevor Carson before netting again in the second half after a great pass from Jota.
David Turnbull then came off the bench to seal his customary goal against the Buddies in an absolute stroll in Glasgow.
