Two stoppage-time penalties saw Celtic edge past Astana 2-1 to reach the Champions League play-off round.
Leigh Griffiths nudged the Scottish champions ahead on the stroke of half-time, but after the outfit from Kazakhstan equalised, Moussa Dembele's first goal for the club - in the 92nd minute - was required to seal the tie 3-2 on aggregate.
Griffiths, the scorer in the 1-1 draw in the first leg, and the club's leading goal-getter last term, stepped up and sent the goalkeeper the wrong way with a cool spot-kick.
But with half an hour remaining Astana offered a riposte, with Agim Ibraimi profiting from Craig Gordon's poor clearance to draw the teams level on the night and in the tie.
Dembele was the man fouled this time, converting the penalty himself to secure Brendan Rodgers' side's progression.
Elsewhere, there were surprise casualties in the third round of qualifying, including Olympiacos, who were knocked out by Hapoel Be'er-Sheva.
