Goal greedy Moi Elyounoussi has admitted he was disappointed not to net a hat-trick as part of his man-of-the-match performance against KR Reykjavik.
The 26-year-old scored a double and was the attacking fulcrum through which much of Celtic 's play flowed as the loan signing showed exactly why Neil Lennon pushed the boat out to get him in place for what will be a crucial season.
Christopher Jullien, Greg Taylor and Odsonne Edouard were also on target, with the visitors scoring an own goal through defender Arnor Adalsteinsson, as Celtic set up a second qualifier, also one-legged, against Ferencvaros or Djurgarden next week.
And Elyounoussi believes that there is "more to come" from Neil Lennon's men.
"I am an offensive player, I like to create chances and score goals," he said.
"So obviously I am happy to help the team to win the game. I should have scored a hat-trick but hopefully next time.
"We played with confidence and got the clean sheet. It was a good performance."
Elyounoussi was glad to see his former Basel team-mate Albian Ajeti, the Swiss striker recently signed from West Ham, come off the bench in the second half to make his debut and hopes they will form a potent partnership again.
He said: "He just came a few days ago. He will need some time to get fit.
"But he is a strong player physically, smart player, very clever in front of goal.
"He had a few assists for me, I had a few assists for him when we played together.
"When he gets fit and gets confidence, I am sure he will score some goals here.
"We know each other well - if we both play we know what to expect from each other.
"All players want to play at the highest level as possible and the Champions League is amazing.
"I really want to experience it with Celtic, hopefully in front of our fans.
"I know those nights here at Celtic Park are amazing.
"I heard it is a few years since Celtic played in the Champions League.
"It is a huge goal for us. We are going to try everything to reach that goal and obviously the cup and the league as well.
"We have the squad for it, we believe in our manager and coaching team, so this was a good result and we need to focus on the next one."
