It was mission accomplished for Celtic against AZ Alkmaar but they made it through by the skin of their teeth.
An early Kyogo Furuhashi goal looked to have them well on their way to the Europa League group stages.
But they were forced to hang on for dear life after the hosts responded by punishing some poor defending and goalkeeping.
But Ange Postecoglou won't care as he returns to Glasgow for what is a massivew game against Rangers on Sunday.
Here's how the Hoops rated out of ten.
Joe Hart: Horrible mistake but also produce two big saves in either half. 5
Anthony Ralston: Great ball for Kyogo's goal and was great in the air as Celtic defended. 7
Stephen Welsh: Poor header back to Hart for AZ''s first but was much better second half. 6
Carl Starfelt: Wild slice have AZ deserved lead but like Welsh, an improved second half. 5
Greg Taylor: Early injury meant he couldn't really affect the game. 4
Callum McGregor: Tough shift in the middle with little help from his colleagues. 6
David Turnbull: Game passed him by for the most part. 5
Tom Rogic: Wasn't really involved as Celtic struggled to get out of their own half. 5
Ryan Christie: Worked hard but didn't really create much in an attacking sense. 6
Liel Abada: Great ball across for Celtic's opener but influence waned after that. 6
Kyogo Furuhashi: Yet another goal that seemed to have Celtic cruising. Took a knock in the second half. 7
Subs
Adam Montogomery: Stuck to his task really well in an unfamiliar position. good game. 7
Odsonne Edouard: Could see the improvement in Celtic as soon as he came on. 6
Ismaila Soro: Went on to see out the game. 4
